I have an Exchange calendar synced with Mavericks' Calendar app. I've changed time of one event. Since that a window with following message appears over and over:
Calendar can’t delete an occurrence from the repeating the event “[event]” from the Exchange server.
I've tried to re-add the calendar as well as the whole Exchange account. Deleting the
Calendar Cache* files (in
~/Library/Calendars) screws up all calendar data and I'm not able to re-add the synced calendars.
I've all calendars synced in cloud (iCloud, Google, Exchange), so deleting the Calendar files is no issue.
