Good morning!
I'm having an issue at a client of mine regarding a shared calendar. The client is a small clinical practic and the calendar in question is the doctors calendar on which all appointments are scheduled. This calendar has been shared out with three users who all have publishing editor permissions on the calendar. However, when one of the users, lets call her User A, makes changes on the calendar, nobody else can see it. All other users (including the doctor whose calendar it is) see appointments made by everyone EXCEPT User A. User A also does not see any appointments made by anyone but herself. This is all in Outlook 2013.
Now if I log into OWA and create an appointment on the shared calendar as her all other users can see it and she can see the appointments made by all other users? All of the account settings w/ regards to cached mode are the same in Outlook for her as compared with other users so I'm at a bit of a loss to explain this.
