Noticed this in beta 2, but it has continued in beta 3. My exchange calendar is no longer syncing properly with iCal. I've cleared all the cache files and preference .plist, removed/re added the exchange account all to no avail. Symptoms: - If i create an event on iCal in exchange, it will sync over to my work outlook account like normal - If i create an event in my work outlook account, it never shows up on iCal (this used to work) - Mail still functions normally everywhere so I know my account info is correct If I add the exchange calendar to my Mac Mini, which I don't have any accounts on as it just serves as a media host, it updates just fine. Which leads me to believe it's something on my laptop that's causing a conflict. Has anyone seen this or has fixed it before? I've exhausted all of the "my exchange calendar wont sync" articles that are online but they are all for 10.11 and earlier. --- Post Merged, Nov 14, 2016 --- I've even trashed the entire Calendars folder in ~/Library/ & the preferences .plist and still will not update. Not sure what else is clinging on.
