Outlook XP Registry Key change

Hello,

I am wondering if anyone can tell me the registry key that
needs to be changed in order to remove the check in the
checkbox under Tools->Options->Edit, for using the CTRL-
Click feature in Outlook XP in order to follow a
hyperlink. I have approximately 800 machines to alter and
doing it for every machine individually would be a waste
of time. I can push the change with my LAN management
software if I knew what reg key to change. Thanks for the
information in advance.

Nelson
