Errors in the OST (Offline Storage Table) file can disrupt your access to Outlook emails and other data. These errors are typically caused by issues such as abrupt system shutdowns, synchronization problems, or corrupted files. Here's how to fix errors detected in the OST file:
Step-by-Step Guide:
1. Use the Inbox Repair Tool (Scanpst.exe):

• Close Outlook and locate the Scanpst.exe tool on your computer (usually found in the Outlook installation directory).
• Open Scanpst.exe and browse to select your OST file.
• Click "Start" to begin the scan. If errors are found, choose "Repair" to fix them.

2. Recreate the OST File:

• Close Outlook and navigate to the OST file location.
• Rename the corrupted OST file (eg, add .old to the filename) to prevent Outlook from recognizing it.
• Restart Outlook. It will automatically create a new OST file and synchronize your mailbox data from the server.

3. Use Professional Repair Tools:

• Consider using third-party OST repair software if built-in tools do not resolve the issue. These tools are designed to handle complex corruption and recover your data effectively.

4. Check for Updates:

• Please make sure your Outlook and Windows are current, as updates often have fixes for known issues.

By following these steps, you can effectively address and fix errors in your OST file, restoring smooth access to your Outlook data.
