I have a user running Windows XP SP2, Outlook 2003 SP1 who is unable to see a shared calendar on his computer. The permissions are set up properly by the person who is sharing their calendar. If I log on as the user at my own personal workstation and bring up Outlook, I can see the shared calendar. I deleted the Outlook profile on the users workstation as well deleted all the associated Outlook files (*.oab, *.ost, etc) and created a new Outlook profile for the user. No change in inability to view shared calendar. Is it possible that the Windows profile is corrupt somehow?
