After upgrading from Office 2003 to 2007,Outlook locks up while loading for the first time. I have uninstalled and resinstalled, ran a repair and toatally removed office and installed fresh. I was told by our helpdesk to "Close outlook, control panel, mail, click show profiles, then delete any profiles. Of note any extra email accounts or calendars(sometimes these comeback) will have to be re-added". The only problem with that is, there is no mail to click on in the control panel. Does this mean there is a problem with Windows? I am running XP SP3.
