I have a computer running Windows XP SP3 and Microsoft Office Suite 2007. All office applications seem to run properly except Outlook. I can open Outlook when I first boot the computer and the Outlook icon will appear in the system tray (bottom right corner) looking like the program is running. If I close Outlook the icon remains but is greyed out with an X through it. I then can no longer open Outlook. I have tried to fix this problem using the repair option from Add/Remove programs, from the original installation disk and the Diagnose and Repair routine in Outlook itself. I have run out of ideas. I have run virus scans, chkdsk, and scandisk but nothing seems to help. I have run out of ides. Please advise.
