Hi,

I have experienced the very same.
I have Office 2003 on Windows XP SP2 and installed OneNote 2007. First I didn't realized that there may be any connection between the installation and the Outlook misfunctions. After reading your posts, I removed OneNote at once. At the and of the removal process, I was asked to insert the Office2003 setup media for loading a cab file (unfortunately I didn't noticed the name of it).

The uninstall solved my problem, Outlook 2003 works the same way as before.

Thank you for the suggession.

Kalman
