Olav,

Sorry I don't have Outlook 2000 installed so I can't give you step by step instructions.

I don't find that key on my WinXP box either. I have HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows Messaging Subsystem\MSMapiApps

I'm not sure where you can get a definiive list of keys for all current versions of Windows.

>Can't seem to find this option under Tools/Options in Outlook 2000. Do you know where it can be found there?

>Will setting this option (in Outlook or OutlookExpress) create the MAPI Profiles key (Software\Microsoft\Windows Messaging Subsystem\Profiles) in the registry if it doesn't already exist?

>Also, will the the MAPI Profiles key differ under different versions of Windows? (Please specify which key under which version.)
