Causes of “Outlook ScanPST.exe does not recognize the file” error prompt

files, you are still provided with a built-in repair option (to repair and
recover files), in case of damage or corruption.

Overstretched PST File Limit
frequent users of Microsoft Outlook might end up consuming a lot of storage
space, getting PST file size larger that the defined limit depending upon the
Outlook version. This is even worse for critical Outlook users who send and

Affected files, in this case, usually become inaccessible. And if the damage is severe, the Outlook Repair tool might not recognize the files while trying to fix the damage.
Damaged Hard Drive
Hard drive is the primary
storage hub of a typical computer system. As such, any damage to the hard drive
is likely to have ripple effects on Outlook PST files and even back-ups. If the
damage is severe, the in-built scanPST tool might not even recognize it,
talkless of fixing it.
Using Unreliable Tools
Using untested or unreliable
utility tools, either as a file transfer medium or as a compression tool, might
damage your PST file.
However, in this case, using
unreliable repair tool is the main culprit. If you are trying to fix a damaged
file with an unreliable repair tool, you would only end up aggravating the
damage even more. Such file damage is usually too severe for the MS Outlook
built-in repair tool to fix.
This is why it is recommended to always use reliable PST repair tools. And we’ll be looking at how to fix the “Outlook Repair tool does not recognize the file” error, using a reliable PST repair tool, in the next section of this blog.
