I want to remove Outlook express from our Windows 2003 servers but not sure if Outook 2007 will work properly.  I followed microsoft kb: http://support.microsoft.com/kb/263837.
It mentioned only Outlook 2000 will NOT work..but doesn't say if Outlook 2007 will work or not.  Note: in the Knowledge base, it said not to rename or replace Csapi3t1.dll, Directdb.dll, and Inetcomm.dll, which I didn't.  Does anyone know if Outlook 07 will work functionally if I followed microsoft's kb 263837?

I would HIGHLY suggest that you don't remove Outlook Express from a Windows 2003 Server system.  Even in the article you referenced MS says:

"Do not remove Outlook Express from a computer that is running Microsoft Windows Server 2003. Some Microsoft programs that run on Windows Server 2003 depend on Outlook Express to work correctly. For example, Microsoft Operations Manager will not send e-mail alerts if Outlook Express is removed from a computer that is running Windows Server 2003."

Many of the Windows 2003 Server sub-components (such as the CDO) rely on functionality provided by Outlook Express, you're putting your system at risk by removing it.

Interesting...
My apologies, I should have explained on why I'm trying to remove Outlook Express.  Basically, everytime a new profile logs into the system, Outlook express reappears....No matter how many times your remove the shortcut.  Any suggestions?

Thus far, I removed the three reg keys as suggested.
hkey_local_machine\software\microsoft\outlook express
hkey_current_user\software\microsoft\outlook express
hkey_local_machine\software\microsoft\active setup\installed components\{44BBA840-CC51-11CF-AAFA-00AA00B6015C}.
And renamed the files: msoe.dll to .old, msoeacct.dll, msoert2.dll, msoeres.dll, msimn.exe, oeimport.dll, oemiglib.dll, oemig50.exe, setup50.exe.
As of now, every new profile that logs in no Outlook Express shows up...But does this mean I broke any values for Outlook 2007 and MOM to work in the future?

after uninstalling remove delete the users local settings\application data\microsoft\outlook folder

I highly doubt the poster is coming back - but I'm not seeing what the point of deleting that folder would be since it wouldn't remove Outlook Express.  The only beinifit I could see is that the identity folder would be removed, but that's going to be empty anyway since no one actually used Outlook Express on the server.

We used a registry key to stop Express from loading...

Is it the registry key I mentioned?  If so, please accept my answer and close the question.
