Some Events Not Syncing With All Apps
LisaHendrickson, that's interesting. In Apple calendar, my default calendar is set to "Selected Calendar". If you create an event on the Office365 end, does it replicate to the Apple calendar? Earlier today, I found that I was missing a handful of events in the Apple calendar, but now they are there. I did request a sync at the time, but nothing immediately happened so maybe it just took a while. I'm not wondering if I select a different calendar, do Office 365 events sync? I'd hope that it doesn't work that way - I shouldn't have to do anything to get calendars synced across. Yes, if creating them at either end I need to create them in the correct calendar. I've been doing this regularly with 3 different calendars for several years.
I turned off all my calendars but the Exchange, so when I see it "selected calendar", it shows me an orange "calendar" which is just Exchange for me. You probably have a few calendars. You should not need to hit sync as Exchange does it automatically. Gmail/iCloud also should run automatically. Take a look at all the accounts in the calendar accounts area. Gmail, Exchange, Yahoo, iCloud, outlook.com all can have a synching calendar, that might be some of the confusion.
LisaHendrickson, I have 2 Exchange calendars, 2 Google calendars, and an iCloud calendar. All are set to sync, but it's seemingly only the Exchange ones that stop, or miss some updates for whatever reason. I should be able to trust that the calendar app is showing me everything, but since I can't, I have to use Outlook. I've just noticed though, that Outlook is not displaying repeating events from a Google shared calendar. Changing the name of the event in Apple Calendar then results in them being displayed in Outlook, although changing them back doesn't reliably get them to update in Outlook again. So at least for me, sync just seems to be unreliable.
Other than what you've done, you could be having a security issue and it's glitching. Do you have business 365 or an outlook.com/hotmail.com account? If security is not tight, the bumps happen.
Both of the synced 365 accounts are Business and both are configured with MFA. I do have an Outlook.com account (as a recovery email for my gmail account), but it is not synced with Calendar. I have no issues with email for the business accounts - just calendar sync. If there were security issues, I would expect to see some form of error somewhere, but it may just be that they never considered that users would need to see them. I think it would be interesting to try another calendar app to see if the same issues occur there (it would have to be using it's own sync engine though). It might help point to where the problem lies.
