If you’re an Outlook user and facing issues accessing your mailbox data, chances are your PST file is corrupted. PST (Personal Storage Table) files are the backbone of Microsoft Outlook, storing emails, contacts, calendars, and more. When these files get damaged, it can lead to serious data accessibility issues. Thankfully, repairing a PST file is possible through both manual and professional methods. This blog will walk you through the causes of PST corruption and how to repair it step-by-step.
Common Reasons for PST File Corruption
- Before jumping into the solutions, it’s important to understand why PST files become corrupt or inaccessible. Here are some common causes:
- Oversized PST File: Older versions of Outlook have file size limits. Exceeding them can corrupt the file.
- Improper Shutdown: Unexpected system crashes or improper Outlook exits can damage PST files.
- Virus or Malware Attacks: Malicious software can directly impact PST file integrity.
- Hard Drive Failures: Bad sectors or drive corruption can affect the files stored within, including PST.
- Software Conflicts: Third-party add-ins or conflicting software can cause file corruption in Outlook.
