Repairing a corrupted OST file in Outlook depends on the extent of the corruption and the accessibility of your mailbox. Here are the most effective methods you can try:
- Restart Outlook and check your internet connection
- Run the Inbox Repair Tool (ScanPST) for minor issues
- Delete and recreate the OST file (most effective)
- Disable add-ins that may cause conflicts
- Create a new Outlook profile if needed
- Convert OST to PST if the file is inaccessible
Conclusion: Recreating the OST file usually fixes the issue, but for severe corruption, the BLR OST Recovery tool is the best option.
