We run Outlook 2003/2007 and Exchange 2000. We have a shared calendar for one of of conference rooms. I had someone who had permissions issues with it (she could create but not delete items) so I changed the password for the calendar username in AD. Then I logged into outlook as that username and gave full permissions for it's calendar to her. The problem is, now as far as I can tell nobody can do anything on the calendar. You try and create an appt. and it says "Object could not be found". Why would that happen just because of a password change and how do I fix it?
