Hello Jeff,  Try to use these Keys:  HKCU\Software\Microsoft\Windows NT\CurrentVersion\Windows Messaging SubsystemHKCU\Software\Microsoft\Office\11.0    
I have set up 5 Virtual Desktops with Office 2003 installed.  However, I cannot get the User Profiles to push the Outlook 2003 configuration.  I have configured User Profiles for the following registry:  HKCU\Software\Microsoft\Windows NT\CurrentVersion\Windows Messaging Subsystem HKCU\Software\Microsoft\Office  However, whenever I launch Outlook, it goes through it's initial setup first and I have to create a new profile.  What am I missing?  Thanks,  Jeff
