Administrative install - Outlook only

I have a need to create an administrative install of Outlook 2003 (part of a migration to 2007 by the way). I run through the steps of setup /a, enter the key and accept the agreement. I then run the Custom Install Wizard and point it to the admin install on the server. On step 7 of 24, it prompts me to select the default installation state. I "X out" Word, Excel, etc...all but Outlook. Continue on with no errors and all seems well.

I then run, from a command prompt on a PC, the line generated for me; similar to this:
setup.exe TRANSFORMS=I:\Outlook2K3\Outlook2K3Only.MST /qb-

but the entire Office suite gets installed each time. Any idea what I'm doing wrong?
