I have a few exchange 2000 users on outlook 2003 who lose the ability to create/access/edit appointments in their own calendar from time to time.
It's periodic problem and I have been unable to recreate it or force it.
When the problem arises, the user is still able to create appointments in shared calendars. And others have no problem creating appointments in the users calendar.
I have tried upgrading said clients to SP3 with no succes, I have tried rebuilding the .ost, reinstalling outlook, /cleanreminders, /cleanfreebusy but the problem persists. MS support have tried to assist me but came up empty.
If Outlook is closed after the problem arises, the outlook.exe process keeps running. If outlook.exe process is terminated and Outlook restarted everything works.
I thought I would give it one last chance before moving the troubled users to Outlook 2007.
If you need additional details please let me know.
