Microsoft Outlook Personal Folders Format is supported by 1 operating systems. Although it can be found with greater or lesser success on any operating system, it will only be useful on Windows. The main program that supports this format is Microsoft Outlook. This was created by Microsoft Corporation. Alternatively, you can use 3 other programs. Microsoft Office, Microsoft Exchange Server, Office 365 will apply when it is not possible to use Microsoft Outlook.

How to open XST file?

The most common problem when using Microsoft Outlook Personal Folders Format is that a specific XST is not associated with the program. This causes the file XST to open by system applications not designed for this purpose, or to display a message that there is no associated program. This problem can be easily remedied.

The first thing you should do is just "doubleclick" on the XST file icon you want to open. If the operating system has an appropriate application to support it and there is also an association between the file and the program, the file should be opened.

Step 1. Install Microsoft Outlook

The first step is to check if the computer has the Microsoft Outlook program installed. This can be achieved by typing Microsoft Outlook into the operating system search engine. If we do not have this program, it is worth installing it, as it will help you automatically associate the file XST with Microsoft Outlook. Below you will find a list of applications that support XST files.

Step 2. Create association of Microsoft Outlook with XST files

If, despite the installed application, the XST file does not start in the Microsoft Outlook application, you must create a file association. This option is available from the level of Properties of a specific file available in the context menu. The window will show, among other things, the type of the file and the information by which the program is used to launch the file. Using the "Change" button we can set the program to handle this type. The program should be visible in the window, otherwise it should be selected manually using the "Browse" button and the program installation directory should be indicated. However, it is important to check the "Always use the selected program ..." box, this will allow you to permanently associate the XST file with the Microsoft Outlook application.

Step 3. Update Microsoft Outlook to the latest version

The fault may also lie with the Microsoft Outlook program, it is possible that Microsoft Outlook Personal Folders Format requires a newer version of the program. Some applications allow you to update from the program level, and for others you need to download the installer from the Microsoft Corporation page and install.

Step 4. Check for the following problems with the XST file

If the above steps do not help, you can assume that the file itself is not correct. This could be due to the file itself, the cleanest issues are:

Very often, the file may be size 0 or incomplete. This is most often caused by a problem while downloading the XST file. The file should be downloaded again, making sure that the process has finished correctly.
The most common cause here is computer viruses. A virus scan using an up-to-date antivirus program should fix the problem. Alternatively, you can use the scanners available online. For the best results, we will scan the entire operating system, not just our XST file. As a result of the scan, sometimes it is not possible to recover XST files, which are deleted if there is a backup of this file, then after restoring it, it must also be scanned.
Older version of XST file may not always be supported by the latest software version. On their websites, developers usually offer free solutions to such problems, e.g. in the form of a conversion program or an older version of the program.
The file may be corrupted in a number of ways. The repair method must be adapted to the type of file and damage. Some programs offer the ability to automatically repair XST file corruption. You can restore the file from a backup or use Microsoft help.
When reading, a message appears that the file was encrypted or corrupted. The encrypted XST files can be used by the device on which they were encrypted, on any other device it is required to have the appropriate cryptographic key and decrypt the file before its recovery.
Some of the system directories are excluded from modification. While there is usually no problem reading such a file, it may not be possible to save it. Copying the XST file to another location will fix the problem.
This problem usually affects more complex files. Some file types can only be opened in one program at a time. Running programs (including those in the background) should be verified. If the error persists after closing other programs, wait for a while. However, some background programs may block the XST file while scanning. If this does not work either, restart the device.
