2. Try to open Outlook in safe mode

Try opening Outlook in safe mode

1. To start in safe mode, hold down the key while opening Outlook CTRL. (Hold it down until a message appears.) Or press the button Start and in the search or execute box type outlook.exe /safe and press the key ENTER.

2. If Outlook opens, most likely an add-in is causing the problem. In Outlook on the menu File select item Parameters, then press add-ons. At the bottom of the screen where it says Manage, click jump, and on the next screen, uncheck the boxes.

3. Disable all add-ons. After that, you can start the Outlook application again and check if it works. If so, you can enable add-ins one at a time until Outlook crashes again. The most likely source of the problem is the add-on that you enabled last. Uninstall or reinstall this add-on.

3. Use scanpst.exe to fix Outlook data file errors

If Outlook won't open in safe mode, the issue might be caused by a corrupted PST file or profile.

In a PST or personal storage folder, also known as a file .pst, Outlook stores messages, contacts, appointments, tasks, notes and journal entries

1. Find the PST file by opening the section mail on the panel Windows controls. Click the button Data files.

2. If there are multiple PST files, pay attention to the flagged file. This is the default value.

3. Navigate to the path indicated in the Data Files window. For example, C:\Users\robinxxxxx\AppData\Local\Microsoft\Outlook

4. You will need to check the box Show hidden files, folders and drives and uncheck Hide extensions for known file types.
For information on how to change these settings, see the Microsoft article Show hidden files.

6. Rename the extension .pst in .psp.

7. Try to open Outlook again and double-click OK when prompted during startup. As a result, a new PST file is created. If Outlook opens successfully, this indicates a problem with the original PST file.

8. However, if the application fails to open with the new generalized PST file, then the profile or Outlook is corrupted. Proceed to the next section.

9. If Outlook opens, rename the file .psp, specifying the extension again .pst.

10. Try to run the scanpst.exe tool on the source file and run the test.

11. Try opening Outlook again. If you still have problems with the PST file, you can perform further recovery by following the instructions in the following Microsoft article: Recovering Outlook Data Files (.pst and .ost) .

4. Restore your Outlook profile

If Outlook still won't open with the generic PST file, it might be due to a corrupted profile. You can try to restore it from the Control Panel.

mail, then press Accounts Email .

2. Tab Email in the Account Settings dialog box, highlight your account, and then click Restore.

3. Follow the instructions of the recovery wizard.

4. Press the button Ready. After the restore is complete, restart Outlook.

Another way at this point is to copy an existing profile and see if it opens.

1. On the control panel, select the section mail, and then click Show profiles.

2. Click Copy, enter a new name for the profile, for example, add 1 at the end.

3. Select a new profile from the drop-down list below the radio button Use configuration, and then click the button OK.

4. Try restarting Outlook.

5. Create a new Outlook profile

If Outlook still doesn't open with the generic PST file, and the copy and restore functionality fails, create a new profile.

1. On the control panel, select the section mail, and then click Show profiles.

2. Click Add and enter a name for the new profile.

3. Before pressing OK, select Request configuration.

Microsoft Outlook- one of the most popular email clients on the market, known for its convenience and versatility. However, while working with it, certain errors may occur that prevent the use of the program.

Launch problems

In the process of turning on mail client may give an "Outlook is not responding" error or hang while processing, making it impossible to continue working with it. If this happened once, there is nothing to worry about: you can simply restart the program, and everything will go as it should. But constant failures may indicate problems in the program that need to be addressed.

Before you start "fixing" the program, make sure that the problems are not caused by one of the following reasons:

availability of open dialog boxes, not noticed by the user and interfering with actions;

execution of a long complex operation by the program - this can cause a hang that will stop when the operation is completed;

an update that has not been carried out for a long time, due to which errors can accumulate in the program.

If everything is in order with this, you can proceed directly to the ways to fix the problem.

Entering Safe Mode

Safe mode allows you to work with the program even in situations where normal mode she refuses to start. In some cases - for example, if the application freezes during the "Processing" phase - starting in safe mode helps to troubleshoot.

The easiest way to start Outlook in safe mode is to open it while holding Ctrl key. As a result, a message should appear asking if you should use safe mode. Click Yes.

Outlook asks if the user is sure they want to start it in safe mode

Another way is through the Run menu, which is called by the Win + R key combination. To start Outlook in safe mode, you need to type outlook /safe in the window. After pressing the OK button, the program will open in the desired mode.
You can use the Run window to make Outlook boot into safe mode

Now you need to disable the COM add-ins, which are very heavy on the program and sometimes cause a hang. Their parameters are located in the "Parameters" - Add-ins - "Management" - "COM Add-ins" window. You need to disable everything unused by unchecking unnecessary items.

After everything is done, Outlook needs to be restarted.

Sometimes it can help to simply open the program in safe mode without any manipulations. This is due to the fact that Outlook cannot always exit the “hung” state even after a reboot, and entering safe mode serves as a kind of “shake” for it.

Working with the scanpst.exe utility

If safe mode did not help fix the problem with starting the program, you can turn to the built-in utility scanpst.exe, which was created to repair damage to the Inbox folder and in some cases can help with Outlook errors and freezes. You need to use it if Outlook cannot open the data file. The program will scan and attempt to repair damaged files so that Outlook can open them again.

The executable file of the utility, like other program files, is stored in the Outlook folder, the name of which may vary depending on the version of the program:

• Outlook 2016: C:\Program Files (x86)\ Microsoft Office\root\Office16;
• Outlook 2013: C:\Program Files (x86)\Microsoft Office\Office15;
• Outlook 2010: C:\Program Files (x86)\Microsoft Office\Office14;
• Outlook 2007: C:\Program Files (x86)\Microsoft Office\Office12.

To fix the problem with scanpst.exe, follow these steps:

Run the file first. A dialog box will appear prompting you to select a file to check. To check and, if possible, restore the data file, you need to specify the path to it in the program and click Start

Depending on the version, the Inbox file (.pst or .ost format) may be stored in different locations. Usually, to find it, they use the regular tools of Outlook itself: data on where the file is located can be viewed by going along the path "File" - "Information" - "Account Settings" - "Data Files".
In the "Data Files" tab in Outlook, you can see exactly where the desired PST file is located

After the file path is specified, click on the "Start" button and wait until the scan is completed.

If the utility finds errors, it will offer to fix them. To do this, click "Restore". If the scanpst utility finds errors, it will notify the user and offer to fix them

After recovery, the files should be put in order. Now Outlook will start seeing them again.

If you use synchronization with a Microsoft Exchange account, then the OST file can be left uncorrected, and if errors are found, simply deleted: Outlook will automatically restore it. Unfortunately, this is not possible with a PST file.

Outlook won't connect to Exchange

A Microsoft Exchange account is an email account that you have obtained from your organization or school. Your organization's IT department has installed a program called Microsoft Exchange Server. This server provides the email service.

Microsoft
http://tinyurl.com/ybgr8hoo

There are hundreds of reasons why the connection to Exchange might not work, and it is not possible to consider them all to a single one. Let's analyze the main, typical connection errors and how to solve them.

Product versions do not match

If the 2016 version of Outlook tries to connect to an Exchange 2003 server, it will naturally fail. To make it work, you need a newer version of Exchange. If you work in an organization and do not have access to the server software, contact your system administrator to update the software.

It also happens that the reason is the absence of any important update for Outlook. In this case, you need to download it.

The entered data is incorrect

The reason for the error may be incorrectly entered account information. You can check if they are entered correctly and change them if necessary inside Outlook in the menu "Tools" - "Accounts" - Your account name. Microsoft also recommends that you try connecting to Exchange using another Outlook product, such as the online version. This will help to understand whether the problem is in the data: if it doesn’t work out there, the problem is most likely in them.

Outlook can't access the internet

Sometimes it happens. The first step is to check the network connection: is there any Internet on your computer at all. If there is, then most likely Outlook is running in offline. You can check this in the Outlook menu: if there is a checkmark " Offline work"So you have to take it off. After that, access should appear.

In addition, it is worth checking if the firewall does not prohibit Internet access to the mail client. If so, he should be given access. Sometimes adding to exceptions does not help, and you have to disable the firewall altogether, but such situations are rare.

If using the standard windows firewall, instructions for adding a program to exceptions are typical. For third-party firewalls (for example, those built into major antiviruses), the recommendations are different and unique for each product: in this case, it is recommended to look for instructions in the documentation.

Go along the path "Start" - "Control Panel" - Windows Firewall.
Windows Firewall is accessed through the "Control Panel"

Find the menu item "Permission to interact with the application ..." on the left and click on it.
To allow any program to interact with the network, you need to click on the corresponding menu item

In the list that opens, find Outlook and allow it to interact by checking the box.

Click OK and exit the program.

Video: How to add an exception to the firewall

Server is not available

There are two ways to check if the server is available. The first is to connect to it using another Outlook application (for example, online) or ask if the connection is available to other users of the same server if you are familiar with them. The second is to look into the settings: "Service" - "Accounts" - "Exchange Account". If there really is no access to the server, this will be reflected in the account properties.

Sometimes Outlook can tell you about the unavailability of the server itself. In this case, all that remains is to wait until his work is restored.

Requires encryption or proxy

It happens that there is no access to Exchange, because the server is configured only to connect via an encrypted channel or through a proxy. As a rule, in new versions of Outlook for Windows, everything is configured automatically, and the problem most often occurs when working with Mac or older versions. In the case of a proxy, the data must be asked from the network administrator, and the encrypted channel is configured as follows.

If you are using a Mac, go to the path "Tools" - "Accounts" - the name of your account - "Advanced" - "Server".

Check the boxes "Use SSL to connect" in both tabs: Microsoft Exchange and Directory Service. To enable SSL in your Exchange account, you need to check the corresponding settings

If the problem arose on a client under Windows, the desired path is: "Tools" - "Accounts" - "Exchange Account" - "Settings" - "Other settings" - "Connection" - "Proxy server settings". In the window that appears, check the "Connection via SSL only" checkbox.
In Outlook for Windows, SSL is enabled by a checkmark in the corresponding settings

Outlook forgets password

If the system constantly asks you for a password when logging into Exchange, and you are tired of entering it every time, the problem is most likely in the authentication method settings. In addition, problems with the password may arise if it is not saved in the profile.

There are other ways to solve password errors, but to use them you need to have administrator rights to the Exchange server - and ordinary users usually do not have them.

Changing the Authentication Method

Different authentication methods require different frequency of password verification. If the password is requested too often, then most likely the method used is not optimal, and it needs to be changed.

You need to go along the path "Service" - "Accounts" - "Exchange account" - "Settings" - "Other settings" - "Connection".

First you need to check if there is a checkmark next to the item "Connection via HTTP protocol". After that - go to the proxy server settings. In the "Connection" tab, the "Connection via HTTP protocol" checkbox should be checked

In the "Authentication Options" item, you need to specify the option "NTLM verification", and in "Security" - "NTLM password verification".
To run an NTLM check that does not require a password each time you connect, you need to select the required item from the drop-down list

Now it remains to apply and save the changes and restart Outlook.

Saving a password in a profile

It happens that the password used is not stored in the user profile. In this case, there may be problems when entering it, which can be solved by manually saving the password.

Press the Win+R key combination to open the Run window.

In the window that opens, type the control keymgr.dll command. The utility window will open.
The built-in window that opens Windows utilities looks something like this (may differ in different versions OS)

In the window, click the "Add" button and specify the data from mailbox: login and password. In the "Server" field, sometimes also called "Internet address", enter *.exch.hc.ru. If you are prompted to select a credential type, select Account for Windows.
You need to enter your account information in special utility from Windows so that Outlook remembers the password

Restart Outlook.

Profile loading hang

Newer versions of Outlook may experience the program hanging on loading at the "Loading profile" stage. This problem can be associated either with a “raw” or low-quality update (only a reboot or a new update will save here), or, oddly enough, with video card drivers. This hang usually occurs when hardware graphics acceleration is enabled in Outlook. Its cause is a conflict between the driver and regular means accelerations that are mutually unsupported.

The easiest way out is to disable hardware acceleration in Outlook safe mode (how to enter it is described in detail above), and if it is impossible to enter it or a parameter cannot be changed in it, use the registry editor.

How to disable hardware acceleration through the registry

Press the Win + R key combination to open the Run window and enter the regedit command in it. Will open system registry Windows.
The window for interacting with the registry looks like this; to go one way or another, you need to open the folders on the left one by one

Navigate to HKEY_CURRENT_USER\Software\Microsoft\Office\your version of Office\Common\Graphics\.

From the registry menu, select "Edit" - "New" - "DWORD Value".
A binary value in the registry is created by right-clicking on the field and selecting "New - DWORD Value"

Name the created element DisableHardwareAcceleration and give it a value of 1. This will disable hardware acceleration and eliminate the conflict between the video card and software. If such an element already exists at the specified location, simply change its value to 1.

Restart Outlook.

Driver update

Despite the fact that disabling acceleration seems to solve the problem, Microsoft company recommends updating your graphics card drivers - this will help solve the problem in the long run, and also allow you to use hardware acceleration without fear of freezing.

Driver updates are usually done through Device Manager. To open it, you need to press the key combination Win + X and select "Device Manager" in the menu that appears. By pressing Win + X, a menu will open where you need to select the appropriate item

In the device manager, find the "Display adapters" item. All graphics cards installed in the system will be listed here. That's what they need to update the drivers.

To do this, right-click on the selected device and select "Update Drivers" in the drop-down menu.
To update the driver, you need to right-click on it and select the "Update" option.

The utility will display a menu prompting you to either run automatic search driver on the Internet, or specify the path to a file already downloaded by the user. If you already have a video card driver file downloaded from the Internet, you can offer the utility to use it. If not, choose to automatically search for drivers on the network. If updates exist, the system will find them and install them.
The utility offers to either indicate to it the path to the already downloaded driver, or let it search for it on its own

After updating the drivers, the problem should be fixed.

Video: how to update drivers

Message store not opening

The message store is the second name of the PST file, which stores information about messages. Most often, the reason for the inability to open it is damage. You can fix them using the scanpst.exe utility.

But sometimes it happens that the file is not damaged, but the message store still does not open. In this case, the cause is usually compatibility mode. Check the Outlook.exe executable file: if its properties (RMB - "Properties") indicate compatibility mode with more early version system, turn it off. It is because of it that errors occur in reading the message store.

In the "Properties" of the executable file there is a checkmark "Run in compatibility mode", which must be unchecked to disable this mode

Can't access file

The file cannot be accessed error usually appears when trying to send or receive a message and means that there is some problem in linking the profile to the folder. Except for the obvious - to scan the data file using scanpst.exe, you can try to unlink the PST file from the profile, and then re-link. The solution will not work if Outlook is bound to the Exchange server via MAPI.

Go along the path "File" - "Account Settings" - "E-mail" and in the window that opens, select the option "Change folder". Be sure to remember where you were. previous file data: then you have to return to it.
To fix the error, you need to reconnect the file; this is done in the account settings

Select the item "New Outlook Data File" and create a new file - it will be temporary, so you should not bother with its name and location. There should be a folder in it: it is usually created by default, but if not created, create it. Select this folder and click OK.
In a freshly created empty file, you need to create a folder and select it as the main one, in order to change it back to the old one later

When the new file is created and linked to the profile, save the changes, and after that go back to the "Change Folder" window and return to using the old data file.

After that, the problem should be resolved.

The security certificate could not be verified

An annoying error that pops up every time you start Outlook, often appears when Outlook interacts with Mail.Ru servers. In addition, its cause may be the use of IP addresses instead of domain names when setting up the server. To fix the error, you should go to the account settings ("Tools" - "Account Settings" - your account - "Change") and change the server names for incoming and outgoing mail there. Domain names are unique to each e-mail search engine and are usually listed in the "Help" section of any of them.

In the account settings there are fields "Incoming mail server" and "Outgoing mail server", which indicate the names of the servers

Sometimes disabling SSL encryption can also help (where to find its settings has already been described above). But do not forget that in this case the connection may become insecure.

Reinstall without data loss

Outlook organizes mail by date received, by folder, and by category. I would not want to lose all this structure by reinstalling the program: letters will be loaded back when the user reconnects email, but their entire hierarchy, from the date to the notes, will evaporate.

Fortunately, all email data is stored in the PST (or OST) file we already know, and before reinstalling it can be moved to another location, so that later it can be returned and reconnected to the account. How to connect files, we have already said earlier.

Video: Data File Transfer

Saving accounts through the registry

In addition to personal folders, you can also save account settings during reinstallation. This is more complicated, and to solve such a problem, we need a system registry. Information about Outlook accounts in the registry is located in the following branches:

• HKEY_CURRENT_USER\Software\Microsoft\Office\Outlook\OMI Account Manager
• HKEY_CURRENT_USER\Software\Microsoft\Windows NT\CurrentVersion\Windows Messaging Subsystem\Profiles\Outlook;
• HKEY_CURRENT_USER\Software\Microsoft\Office\Office Version\Outlook\Options.

To export files from the registry, select one of the above data paths and select "File" - "Export". Specifying the name and location of the file with registry data, we get a file with the extension .reg - registry data. To export one or another branch of the registry, stand on this branch and select "File" - "Export"

We repeat this manipulation with three specified addresses. There should be three files.

Reinstall Outlook; Before reinstalling, you can not touch the files.

When the program is reinstalled, we launch all three REG files one by one for execution (using context menu: RMB - "Merge" or just double click). The data will be automatically embedded in the registry, after asking your permission (you need to agree). To run the registry file, you need to right-click on it and select "Merge" or simply double-click on it

Now, when opening a reinstalled Outlook, all the settings of his accounts will be in place.

outlook- handy program, albeit complex. However, when working with it, the user may experience certain difficulties that it will be difficult for a beginner to deal with. But if you do everything carefully and do not neglect the training instructions, you can learn to cope with any mistakes with a bang.

The service for working with mail messages Microsoft Outlook is very popular among analogues. Users prefer it because of its ease of use and support for most mail systems. But like other programs, Outlook can experience errors and problems. Let's figure out how to deal with them.

Problems starting Microsoft Outlook

If the program refuses to even run on your computer, this problem definitely needs to be addressed. There are several reasons for this, but let's start with the most common ones.

Microsoft Outlook freezes while processing

After the incorrect termination of the program, the next time it is started, it may hang at the processing stage. To fix this error, just run the program in safe mode. It is done like this:

The next time you open the program, it should not hang at the "Processing" stage.

Microsoft Outlook is not responding and will close

If the problem is characterized by a standard error message, there may be more than one solution.

Automatic repair of damaged files

In case of an error during startup, it can help automatic means fixes. To run it, do the following:

These steps should correct your error. If it doesn't, move on to the next solution.

Fixing incoming messages with scanspst.exe

The program's data files might have been damaged when the email was opened. In this case, a data recovery program will help you. To run it, do the following:

1. Close Microsoft Outlook.
2. Open the disk partition on which the program is installed, select the Program Files or Program Files (x86) folder.
3. Enter the name of the executable file Scanpst.exe in the search bar.

   In the search bar, enter the name of the executable file Scanpst.exe

4. In case your system did not find the file, search again in another Program Files folder. This file is typically located at C:\Program Files\Microsoft Office\Office12 for 2007 or older versions. In more recent versions of the program, the file is installed in hidden folders along the path "C:\Users\user\AppData\Local\Microsoft\Outlook".
5. Once the executable is found, run it.

   Run the executable Scanpst.exe

6. After launching, the program will prompt you to select a file to restore. You can click the Browse button to see them all. If you don't know which of the files might be damaged, check each file one by one.

   If an error is found, a notification will appear with the corresponding inscription.

7. If an error is found in the file you have selected, the option to restore the file will appear.
8. After the recovery is complete, restart your computer and try running the program.

Create a new Microsoft Outlook account

A user account stores a number of important data. If they are damaged, it makes sense to try creating a new account to run the program. This is done as follows:

1. Completely stop Microsoft's work outlook.
2. Press Win + X and select the "Control Panel" section (or go to it in another way).

   Select the "Control Panel" section from the quick launch menu

3. Select the "Mail" section and click the "Show" button if your operating system is Windows 7 or Windows 8. On the operating system Windows system 10 first open the user accounts section, and then follow the same instructions.

   On Windows 10, you first need to go to "User Accounts"

4. After opening the "Mail" section, you need to create a new profile. Click the Add button.
5. You will be prompted to enter a new account name. Enter it.
6. Then you will need to enter data from your mail service to bind it to Microsoft Outlook.
7. At this point, you can perform a Microsoft Outlook health check. To do this, click "Check account". You will need an internet connection.

   You can check the functionality of the program by clicking "Check Account"

8. After creating a profile, launch Microsoft Outlook and select a new profile.

If this solution works for you, you can delete the old profile and use the new one.

Other Possible Causes of Outlook Errors

There are a number of simple reasons why your Microsoft Outlook may not start or may freeze. These problems are not errors, but should be taken into account if the program malfunctions. They can occur in such situations:

• opening a dialog box: in some cases it may appear that the program is frozen, when this is not the case. The reason why Microsoft Outlook may not respond to your actions is that a dialog box appears behind the active program window. Use the Win+Tab keyboard shortcut to view all open windows. If you find a request from Microsoft Outlook, switch to it and give an affirmative answer;
• performance challenging task: If your operating system says that the Microsoft Outlook process has terminated, you should probably just wait. When processing a large amount of data, the program can create a false sense of termination. After processing is completed, it will resume its work. And forcibly closing the program while processing a large amount of data can just lead to an error on subsequent launches;
• absence latest updates: timely updates of the program are the key to its stable operation. If you are missing permanent connection to the network or you have disconnected automatic update programs of the Microsoft Office package, sooner or later this can become a serious problem and interfere with the work of the program.

Problems connecting Microsoft Outlook to Exchange server

Exchange Server is an email service provided in educational institutions and in enterprises. It allocates to each user its own account.

Consider the most common causes of this problem and how to fix them:

• usage old version server: support current versions programs - a task for your system administrator. Find out which version of Exchange Server you are connected to;
• incorrect information in your profile: make sure that your account information is entered correctly, as well as the server name. To do this, open your account in the "Service" section and check the data;
• work of Microsoft Outlook in offline mode: in the program menu, check the absence of a checkmark next to the item "Offline work". Remove it if it is installed, since it is because of it that you cannot connect to the server;
• Internet connection problems: make sure your computer has a stable network connection.

Microsoft Outlook does not save passwords

If your program does not save passwords and asks you to enter them again each time, then you can fix this as follows:

If your program does not remember the password from the Exchange server, go to the settings and uncheck the box "Use Cached Exchange Mode".

Uncheck "Use Cached Exchange Mode"

If this solution does not help or the program refuses to accept the password (and you know for sure that it is entered correctly), Office recovery will help you using one of the methods given at the beginning of the article.

Microsoft Outlook freezes when loading a profile

This usually happens when there is a conflict between the graphics hardware and the program settings. If you have multiple graphics cards, haven't updated your drivers in a while, or have your Outlook settings not set to disable hardware acceleration, you may be suffering from this issue. You can fix it in two ways.

Program stuck while loading profile

You can solve this problem through the system registry. But remember that you make any changes to the registry at your own risk. An incorrect change may cause computer problems. If you are confident in your own knowledge, do the following:

A more user-friendly solution would be to update your graphics card drivers. You can do this using a program from the graphics card manufacturer (for example, Nvidia Experience) or download the driver yourself from the manufacturer's website.

Can't open Outlook Information Store

This error occurs due to installation on one computer as the most Microsoft programs Outlook and Microsoft Exchange Server. It occurs due to the fact that the Exchange System Manager is included in the Microsoft Exchange program. Its presence on the computer at the same time as Microsoft Outlook causes a MAPI subsystem conflict. The only solution to this problem is to remove one of the two conflicting programs.

This solution is offered by Microsoft, since other ways to configure joint work these two servers do not exist without various errors.

Can't access Outlook data file

A problem like this can occur when trying to read or send messages. To solve it, you need to change the folder where mail will be delivered. To do this, do the following:

The security certificate could not be verified

If, when starting Microsoft Outlook, you receive an error with the text that the security certificate cannot be verified, you can still continue to use the program to access mail service. But this error will appear every time you start, so it's best to get rid of it.

You can click "Yes" in the warning about the problem and the program will continue to work

Exporting Microsoft Outlook Data When Reinstalling the System

When you reinstall your operating system to save all Microsoft data Outlook needs to create a pst file.

Pst file is a file that saves all incoming and outgoing messages, as well as various settings programs and personal data.

Let's figure out how to export files using Microsoft Outlook 2016 as an example. For other versions of the program, the steps are similar. Do the following:

1. IN running program switch to the "File" tab.

   

And Outlook is slow to load and eventually fails to start or suddenly stops working. There are, of course, reasons for this, which we will analyze below and try to eliminate.

Troubleshooting Microsoft Startup Errors office outlook.

Incorrect shutdown

When you try to enter the program, but see a window with the message "Unable to start Microsoft application Office Outlook", the closing process may not have happened correctly before (for example, the computer turned off unexpectedly when the mail client was open). Try to take the following steps:

All this is done so that the program starts in safe mode. Now it can be closed as usual and reopened in the usual way. Everything should work fine.

Sometimes the navigation file in Microsoft Office gets corrupted and Outlook fails to open. The warning message may contain the phrase: "invalid xml format". Try the following:

1. Click C:\Users\username\AppData\Roaming\Microsoft\Outlook.
2. Find the profilename.xml file there and delete it.

IMPORTANT. Folder options must be set to see hidden content, otherwise you won't find it.

Errors during work

Suppose you were working with an email client, and suddenly it freezes, and soon a message appears that the process has stopped and the program will be closed. After restarting, everything repeats again. Below are several ways to troubleshoot.

File recovery

Error receiving mail

Often, a workflow crash occurs while reading received emails. Try doing this:

1. Close the program.
2. Go to system disk C. If you have Outlook 2007, open the Program Files folder and find the Scanpst.exe file there. Sometimes required component cannot be found - Outlook 2013 application and latest versions often saved to C:\User\Username\AppData\Local\Outlook.
3. Once you find the above file, double click on it.
4. Here you need to select the damaged element and restore it (if you are not sure which is the cause of the problem, check each one).
5. Now restart your system and see if the problem is gone.

Account issues

When starting Outlook, did the profile load suddenly stop and the application closed? The source of the problem is probably related to the loss of account data. You can create a new one:

The next time you open Outlook, sign in with your new profile.

In the event that you have problems with searching through emails in Outlook of various versions: the search does not find anything, does not give complete results, does not search through all pst files, etc., the recommendations from this article should help you solve this problem ( recommendations apply to next versions Outlook 2010, 2013 and 2016).

Checking the status of the search index in Outlook

The ability to search through Outlook items is accomplished by building and maintaining an index of all available items. Therefore, first of all, it is necessary to check the status of this very index.

To do this, go to the tab Search and in the section Search Tools select item Indexing states.

In the event that everything is in order with the index, the status should be in the window that appears:

If configuration changes have not been made for a long time, and indexing is still in progress, then there is a clear problem with the Outlook index.

4. Turn off indexing for a Microsoft Outlook item
5. Close the Outlook email client and use Process Manager to ensure that the outlook.exe process is not present on the system

In the properties of OST and PST files, check that their indexing is allowed (this is worth doing despite the fact that their indexing is already allowed in the service parameters Windows Search). For this

Enable indexing in Outlook

Now we need to enable element indexing Outlook, disabled earlier in paragraph 2. Check the box next to MicrosoftOutlook and save your changes.

Give Outlook time to complete the indexing (depending on the number and size of mailboxes and attached PST files). Then try searching.

1. In Outlook, click File -> Options -> Search
2. Click the button Indexing Options -> Additionally
