Outlook Favorite Folders and Calendar Groups not syncing from Exchange Online
All of our users are having the same issue, started with a few users on Jan 4, now every user is affected by the next day. You can add stuff and it will sync to the server, but it will not sync back down to other users. You can see the added items in OWA, but not on the local PC outlook app. I also contacted a 3rd party IT support company to help, since I did all the fixes you listed and some with nothing fixing the issue. After talking with the company, they too were having customers with the same issues. Looks to me it's server side related and not the local machine. We had to temporarily put all users to not cache public folders and turned off Cached Exchange mode. It's a workaround, but it's EXTREMLY SLOW working in Outlook for all users. I hope this issue is fixed soon.
