The remote workstation: has this PC been joined to your domain? If not, join it to the domain, login with your domain account & try setting up Outlook XP again.  However, Outlook XP is a bit old, so it may still fail to authenticate properly with Exchange 2003.

The PC is a member of the domain. While playing around with the config (using ASDM) I actually got Outlook to work through the VPN but I broke everything else. So I went back to the old config. Funny thing is OWA works perfectly.
OWA should work regardless - it's just a simple HTTPS connection.  Outlook directly interfacing with Exchange is another matter, due to authentication methods & the fact Outlook requires a whole lot more ports to be open between it & the Exchange server.  Unless you really think you need all the functionality of normal Outlook when working remotely, I suggest using OWA, since it's connection requirements are far simpler.

The customer requires Outlook to work. Perhaps it isn't an access-list issue but rather a group issue in the config.
Have you tested with: Outlook 2003, on a laptop/workstation that's joined to the domain & logged in as a domain user?

I finally was able to try Outlook 2003 and it worked. Actually I think this was more of a corrupt Windows XP on the test laptop issue than a Outlook or VPN issue.
