I've been trying to figure this problem for hours and cant seem to get it working. I have MS Office 2013 installed on server 2008 r2 and 3 users that have been using Outlook 2013 with no problems for months.
Today one of the user cannot create new appointments for a shared calendar using her server user profile, but after hours of testing, we can add her email to other user profiles on the server and different computer systems and they all work with no problem. It seems that the problem is her local user profile on the server. Is there a way to delete all the Outlook info in her profile to restart it to default? Any other ideas?
