Need help getting Default Email Address

This may be a very dumb question, but I am trying to get the email address of the person logged into the computer. I can get their network login but I don't know how to get their email address. We use Groupwise instead of Outlook on a Novell network.

Thanks!

If it is avaliable it may be in the registry. Try searching in it on a computer you know the default e-mail address for.
