What makes a PST file corrupt or inaccessible?

Outlook PST files are relatively fragile and highly prone to corruption, compared to other mailing platforms. In fact, a minor system glitch can corrupt PST files and render them inaccessible. This explains the reason for the “first line” repair – ScanPST – on offer.

Interestingly, these issues are encountered across all Outlook versions, from the old Outlook 2000 to the latest Outlook 2019. And the causes of these corruptions are also uniform, barring one or two version-specific exceptions.

Anyway, below are the most notorious causes of corruption in Outlook:

  • Malicious attacks; corruption is imminent in the event of a virus or malware attack.
  • System error; especially those associated with storage (hard disk).
  • Overstretched (oversized) PST.
  • Outlook upgrade (from an older version to the latest version)
  • And more.

Typically, a corrupt PST file is rendered inaccessible, as its contents become blanked out from view. Hence, to facilitate recovery, the file first needs to be repaired. And there is an “Inbox Repair Tool” designed just for that.
