I’ve tried the Microsoft office uninstall tool provided by Microsoft (which deletes more items then just control panel uninstall). Now, restart Outlook and check if Outlook synchronization is working. I’m at wits end and Microsoft stopped helping me because they feel the problem is on our end.

However once I joined this computer back to the domain and let it sit for a few days it was also working fine.

This tool is designed to extract mailbox items from orphaned or inaccessible OST files.

During the scanning process, security applications, like antivirus software or Windows Firewall might lock the Outlook data file, leading to the sync issues. To check if the security application is causing the issue, you can temporarily disable the antivirus program or Firewall and then update the folders. If the issue is resolved, it indicates that your antivirus software or Firewall is interfering with Outlook. To resolve this, you can add Outlook and its related processes as exception in your security software or consider switching to a security application that is compatible with Outlook.
