Are you experiencing issues with your Outlook inbox, including message delays and stuck messages in Outbox? If so, you're not alone. One common problem that can cause these issues is a corrupted local cache file (.ost).

Understanding Sync Issues Folder

The Sync Issues folder is where Outlook stores logs about all issues in synchronization of the local cache file (.ost) with the Exchange Server.

1. Open Outlook and navigate to the File menu.

2. Click on the Account Settings option.

3. Select the account that is experiencing issues with mailbox synchronization.

4. Click on the 'Repair' button next to the account name.

5. Follow the prompts to complete the repair process.
