I have a user who has issue with his calendar in Outlook. Outlook version is 2003.
The first time user logs into Outlook he is unable to accept, open or do anything in his calendar.
For example he clicks on New button in calendar, it does not open a new meeting page. If he clicks on an exsiting entry it does not open. He also can not accept meeting invites.
If he re-start Outlook or re-start his PC then every thing works fine.
