OS: Windows XP Pro
App: Microsoft Outlook 2003

Problem: My Outlook suddenly stopped functioning. When I try to launch it,
I receive an error message that says "preparing to install" then I get a
message that says, "Operation failed due to installation problem. Restart
Outlook and try again." I tried to start the "OSE" service in the
Administrative Tools / Services / Office Source Engine. I configured the
startup type to "automatic" and the the "service status" to start, but to no
avail. Outlook still wont install and repair. What am I doing wrong? How
did it just suddenly stop functioning?

Any advice or help will be appreciated. Thank you
