I am using Outlook 2003 with Windows XP. When I try to open Outlook, it locks up. If I can actually open it, it doesn't close. I have to go into Task Manager and close it. But most of the time when I open Outlook, My cursor shows "busy". Then when I click anywhere in the window, it shows the program is not responding. I have downloaded all the service packs, to no avail. Any suggestions?
