why outlook error occurs

MS Outlook data files are highly prone to corruption. That’s why it is important to always backup your data on regular basis. In case you forgot to do so and your PST files become corrupt, you can still repair them with free Inbox Repair tool of Microsoft.

However, since its capabilities are limited, it won’t work in all the cases and you may end up with errors like “Microsoft Outlook Inbox Repair tool does not recognize the file”. Thus, rendering the tool useless.

Given below are some common practices that results in PST corruption of higher level such that ScanPST.exe is unable to handle it:

  • The most common culprit is the Outlook shutdown. Given that how Outlook was exited is a major case in PST corruption. Due to power failure, virus or even deliberate shutdown of Outlook in an improper way, the underlying data files get corrupted.
  • In earlier version of Outlook, the most common concern for users was the allowed PST file size. In Outlook 2000 the limit was 2 GB which was significantly increased to 20 GB in Outlook 2003 & 2007. In the latest versions, you can find this limit to 50 GB. Once the data accumulated more than this limit, the PST file gets corrupted. So, it is always necessary to manage your files and delete unwanted data on a regular basis.
  • PST files are not your network share friendly files. A number of cases has been observed where the PST file has been damaged due to access over network drives. So, it is important to regularly check the network devices and server to prevent the corruption and hence the “unrecognized file” error.
  • Other causes may be virus attack, faulty storage disks, improper execution of files from third-party tools, office upgrade etc.
