YES I have Exchange 5.5 + Proxy working.
Try putting a hosts. file in the users c:\windows dir.
The problem is due to the Outlook client looking for EXCHANGE SERVER NAME
and you need to tell it the IP address.
All I did was write a hosts. file and put in EXCHANGESERVER And it worked.
P.S try this without packet filtering first and then add PF if you need it.
