Exchange calendar not syncing in macOS Monterey 12.3

Every since upgrading to macOS Monterey 12.3, I'm having trouble with syncing my Exchange calendar in the native Calendar app. Note: by Exchange calendar, I mean the Office 365 calendar, a service my university subscribes to.


I am able to add the calendar to the native application and events do show up. But it seems that soon after that, it stops syncing and new events will not show even with a forced refresh.


Any ideas what to do? Is this is bug?

I also have this problem, and it's probably because Office365/Azure indicates my time zone as +1 (CET) instead of +2 (CEST). In my case, manually adjusting the time zone in Office365 was the solution. I adjusted the time zone to something that corresponded to my situation (in my case, I adjusted the time zone from Amsterdam (+1) to Athens (+2).


After deactivating/activating the account including a restart of macOS 12.3.1, everything works properly again!
