Microsoft Exchange Calendars Refuse to Sync on MacOS Sequoia
I had a problem where new calendar events wouldn’t appear in my MacOS Calendar (using Microsoft Exchange account provided by my work). To fix it I had to go to MacOS Settings -> Internet Accounts -> Exchange account and toggle Calendars off (wait a little) then on. It might happen that your Exchange calendars disappear, and don’t appear again. In that case, do it again. After a few tries it will work, because sometimes computers are kind of like trying to start a lawnmower.
P.S. I also tried force-quitting the exchangesyncd
process (it restarts automatically), but I don’t know if that contributed to fixing the issue.
Update: Calendars are gone again, and I don’t know how to make them stay.
