Some Events Not Syncing With All Apps
I'm not sure what "new security" means, but both MacOS and Microsoft 365 are latest versions. Not being properly setup surely would impact all events and not just some. This-morning, I went to Accounts and removed Calendar from the Exchange account in question. I then re-enabled the Calendar and events were slowly synced to the calendar view. It looks like all events have loaded, but the same thing happened a week or so ago when I deleted the account and re-added it. After some time events start to get missed. I've been through this several times now.
An update. I tried killing the calaccessd process since I believe it provides for the sync capability, and when it restarted it's CPU usage went to about 40% for a couple of minutes, and the calendar was updated. I also have access to another Exchange account, which was also not updating, and the same update occurred with it as well. Next time sync stops I'll try with Google calendar as well to see whether the issue is just with Exchange, or whether it's just calaccessd hanging.

I had a meeting series invitation arrive late yesterday and that hasn't appeared in Mac Calendar. I've tried restarting calaccessd, refreshing calendars from Outlook and Calendar, but nothing changes. I can create events, both single and series from both sides, with Exchange and Google calendars and they're all copied across. I can't see anything different about that invitation. I've disabled and re-enabled the Exchange account again and all events are now showing, including the one that previously wouldn't sync. I've seen suggestions of clearing potentially corrupt calendar cache, but I don't see the files they suggest to delete.

I love solid troubleshooting! Good job Ian_Lewis​ please update as you continue. My Mac won't be setup for a bit still, once it's up I'll test it too!
