When the Microsoft Outlook scanpst.exe tool does not recognize the file, it is usually because the Outlook data file is severely corrupt. We have both manual and automated methods that you can use to fix and prevent such errors in the future

Why does SCANPST.EXE Fail to Recognize the PST File?

Following are the possible reasons why the scanpst.exe tool fails to recognize PST files:

  • PST file is severely damaged: If the PST data file is severely damaged then it becomes difficult for ScanPST EXE to diagnose or repair it.
  • Microsoft Outlook Upgrade: While upgrading Microsoft Outlook a few files might not have been properly updated, and the application replaces such files prematurely. As a result, some of the older files might get corrupted and thus become inaccessible. Hence, upgrading Outlook from an earlier version to a later version is also one of the most potential causes behind PST file corruption.
  • Sharing Files over Insecure Network: Outlook files that are shared over an insecure network are very vulnerable to corruption or virus infection.
  • PST File Size limit exceeded: Users who need to send and receive emails regularly might end up consuming a lot of storage space, resulting in an oversized PST file. With time, the emails pile up and the PST file size quota is reached and this becomes a reason for various forms of Outlook data file corruption. As a result, the affected files become inaccessible. If the damage is critical, then the Outlook Repair tool might not recognize the files while you try to fix the corruption.
  • Scanpst.exe is not found: This is a very rare scenario but sometimes this can also be a reason behind “ScanPST EXE does not recognize pst file”. When you try to search for the Inbox repair tool in the search bar, you won’t be able to locate the PST file.

Note: The file location of the inbox repair tool: C:\Program Files\Microsoft Office\OFFICE12

Some other reasons that can lead to ScanPST EXE not working are accidental shutdown of the application, wrong Outlook setup, use of unreliable tools, and a corrupt hard drive.
