Taking control of Outlook from VB6

I am writing a vb app that allows the user to e-mail a contact through the application. This part of Outlook automation I have working. But what I would like to do, is once the e-mail is complete and the user sends it, instead of saving a copy to the outbox in oulook I would like to specify an external dirctory i.e. a client sub director on a file server… This is something I’m having great trouble with at the moment and am sure the answer is stairing me in the face… Cheers!!
