MS Entourage 2004 problems

THIS IS NOT A BASH MICROSOFT THREAD, DO NOT TURN IT INTO ONE AT THE RISK OF BEING TROUTED MULTIPLE TIMES WITH EXTREME PREJUDICE.

Actually, just using entourage is a pain, but I’m having one problem in particular. My mailbox is full and I can’t figure out how to export my old emails into a .PST (personal storage table). The way my new email ssystem is set up, it saves EVERYTHING on the main server. Retarded, as our mailboxes are limited to 100000 kb. Mine’s already 130000 kb. I just want to save my old emails to my HD and still be able to get to them in-program. Simple enough on paper, but it would seem the finer points of this are lost on MS. I’ve checked MS’s online documentation, forums, help topics, etc, and keeping with longstanding MS tradition, these have all proved useless. :*( My company’s tech guy isn’t even sure.

Does anyone know how to do this?
