Outlook OST File Got Corrupted – Any Fix?

rohit1208

My Outlook suddenly stopped opening after my laptop crashed yesterday. Now it keeps showing OST file errors, and I can’t access any of my emails.

I tried the Inbox Repair Tool, but it didn’t really help. Most of my office emails are in that OST file, so I was getting worried about losing everything.

After trying a few methods, I used the Cigati OST Recovery Tool, which helped me recover the mailbox data from the corrupt OST file pretty smoothly. It was easy to use and saved a lot of time.

Just sharing in case someone else is dealing with the same issue.

Yes, a corrupted OST file can often be fixed depending on the level of corruption. Here are some common solutions you can try:

Use Outlook Inbox Repair Tool (SCANPST.exe)
Microsoft provides a built-in repair utility called SCANPST.exe that can scan and repair minor OST file issues. You can locate the tool in the Outlook installation directory and run it against the damaged OST file.
Recreate the OST File
Since OST files are offline copies of mailbox data, you can delete the corrupted OST file and let Outlook create a new one after reconnecting with the Exchange Server or Office 365 account.
Check Outlook Profile
Sometimes the Outlook profile itself becomes damaged. Creating a new Outlook profile may resolve synchronization or OST corruption problems.

If the OST file is severely corrupted or inaccessible, professional software can help recover mailbox data safely. You can try SysTools OST Recovery Tool. It helps recover emails, contacts, calendars, attachments, and other mailbox items from corrupted OST files without data loss. The software also supports exporting recovered OST data into PST and other formats for easy access in Outlook.
