It sounds like Outlook is stuck in a continuous sync state, which usually happens due to corrupted cache, connection issues, or a problem with the OST file. Here are some steps you can try to resolve it: ✅ 1. Restart Outlook and Your Device Close Outlook completely (check Task Manager to ensure it’s not running in the background). Restart your computer and reopen Outlook. ✅ 2. Check Internet Connection Make sure you have a stable network connection. A weak or intermittent connection can cause sync delays. ✅ 3. Clear Offline Cache In Outlook Classic: Go to File > Account Settings > Account Settings. Select your account and click Change. Disable Use Cached Exchange Mode, restart Outlook, then re-enable it. This refreshes the OST file. ✅ 4. Repair the OST File Close Outlook. Navigate to: C:\Users\
\AppData\Local\Microsoft\Outlook Find the .ost file and rename it (e.g., old.ost). Restart Outlook; it will create a new OST file and resync. ✅ 5. Use Inbox Repair Tool Run SCANPST.EXE (found in your Office installation folder). Select your OST file and repair it. ✅ 6. Check Add-ins Disable unnecessary add-ins: File > Options > Add-ins > Manage COM Add-ins > Go Uncheck any non-essential add-ins and restart Outlook. ✅ 7. Update Outlook Ensure you have the latest updates installed via File > Office Account > Update Options. If these steps don’t resolve the issue, the next option is to create a new Outlook profile or check if your mailbox is oversized, which can also cause sync problems. Hope this helps you. If it continues or these steps are too difficult, then I would suggest going to Microsoft.com and choose support. You can chat with the Microsoft bot and can ask to be transferred to a real person. If you have a subscription Microsoft 365 then your support will be free. Merry Christmas John A. Sorry, there was a problem. Please try again later.
