I have set up one of our senior managers with a zimbra account and shared his calendar with his PA who has been given 'manager' status, in order to add, remove appointments etc. His PA set up a number of appointments for him using her calendar (she's still on a learning curve ), but couldn't seem to re-assign them to his calendar. She opened the appointment, selected his calendar instead of hers, tried to save & was faced with an error message (Item "923" does not exist).
Is this a bug or a 'feature'?!
