I have exchange server 5.5 with NT 4 SP6 on the inside of my firewall (version 4.4). I have users on a DMZ. I have a static and conduit statement in place and I can ping the exchange server from the pc's in the DMZ. I cannot seem to figure out the right ports to open up to allow the DMZ users to use Outlook with Exchange Server. POP3 works, but we want to use the exchange server. Can someone tell me what ports need to be open? Thanks

For security reasons, I'd highly recommend you choose a different solution such as OWA for accessing that information. No need opening up more ports to your internal network than you absolutely have to.
