PST files or Personal Storage Table Files are one type of MS Outlook data file, just like the OST files, where the MS Outlook users store all the mailbox items on their computer. The PST files will help you archive older mailbox items and messages through Exchange and IMAP accounts.

The PST file corruption is one of the most common causes behind this error. This usually happens when the data file you’re planning to transfer is damaged or corrupted. In addition, the PST files can face corruption due to various issues:

Exporting MS Outlook Data from Existing PST Files to New PST Files 

If you fail to connect the MS Outlook client to the Exchange mailbox, then all the contents of your MS Outlook mailbox will be stored in .pst file format. Therefore, you should not export the data to the PST files. This is because exporting data to the new PST files from the exiting PST files will cause not only PST corruption but also data loss. You will also receive a “PST file is not an Outlook data file” error. Uni Trends states software conflict is one of the most common causes of data loss.

Uncheck the ‘Read Only’ Attribute 

Suppose you want to access the personal storage table file already stored in a portable drive, removable media, or any other storage media.

Then, from the Properties window in the General tab option, make sure you uncheck the ‘read only’ attribute and see whether you can open the PST files without any error. 

Copy and Store the PST Files in another Location 

To solve this error, make sure you copy the PST files to another location. For example, if the PST files are stored in the default location, from the files from that specific default location and then paste them into another Documents folder. After that, consider opening the Outlook data file and see whether the problem is still there. 

Check the size of the PST File. 

Oversize PST files are one of the most common causes of the “PST file is not an Outlook data file” error. If the system provides you this message while you try to restore a proper backup of the original PST files, check whether the PST files are oversized or not. In other words, ensure that the PST files you want to access come with their permissible size limit. If the PST files are oversized, they will undoubtedly corrupt and create such errors. If the PST files are corrupted, you will have no choice but to repair the corrupted PST files to access the entire file as well as its contents. This is why MS Outlook developers ask the users to pay close attention to the size of the PST files.
