Apple Calendar delegations disappearing/reappearing randomly
Just recently updated an office to osx mavericks. One user since then has had an issue with Calendar. The delegates constantly refresh, and the list is different every time. If I try and select a delegate it will appear on the calendar for a few seconds then disappear. I tried with a different user on the same machine and it works fine. I have tried deleting the cache of the calendar and also deleting and recreating the account multiple times.
Any idea what is causing this issue?
