How do I fix this?
Using Classic Outlook on Windows for personal email, calendar, and contact management
Locked Question. This question was migrated from the Microsoft Support Community. You can vote on whether it's helpful, but you can't add comments or replies or follow the question.
since today it has been finally fixed here, all items have been synchronized and it works like it should.
no action was needed
We are still having the issue.
Everyday, I check the sync log, see the same error.
I will then "clear offline items" for the public calendar. (This takes forever by the way).
After that I turn "Cached Exchange Mode" back on, and select the "download public folder favorites".
Restart outlook
I then check the public folder properties to make sure the last sync was current and matched the amount of items on the server.
After several hours I'll check them again, and find they aren't syncing.
Sync logs, still show the same error.

unfortunately the error is still present here.
Anyone else also still facing the issue ?
maybe any update Gabriel ?
Curious if anyone has seen the fix propagate down to them yet? Still not showing here yet. Please report if you do.
The fix has propagated to us, we only had to relaunch Outlook.
Fix has reached our Servers. Everything works fine.
"The server team that is working on the fix says that it will take a week for the fix to saturate to all the servers. Based on the fix date it should be rolled out to everyone by 2/18/22."
