Outlook 2003 startup script error
 

When I start Outlook 2003 SP2 running on XP Pro SP2, I get an error
when the Outlook Today page is displayed:

Title: Internet Explorer Script Error

Line: 298
Char: 1
Error: Access is denied
Code: 0
URL: outlook:today

Certainly looks like a IE security settings issue, but I don't know
where to look. The computer is part of a corporate domain and I am
logged in as a domain user that has local admin rights.

I have Restored my Advanced Options to default in IE and it does not
help.
