Creating a new MST for Office 2K3 and need help with the default profile variable
 

As stated in the subject I'm working on a new deployment package for
Office 2k3. One of the things that we got wrong in our current package
is that the default outlook profile uses %username% to set up the user
with thier correct mailbox on the exchange server. The problem is that
our usernames aren't straight forward and don't resolve. So everytime a
user logs into a new computer they get the error stating that thier
name could not be found.

Does anyone know of some other vairables that we might be able to enter
in that field besides username that might be more helpful?

Thanks
