You don't really gain anything putting the OWA part in the DMZ. OWA acts as what I call "MAPI-by-proxy" so the number of holes you need to punch in the internal firewall basically denigrates your DMZ.

Is this possible? We're using NT 4 with Exchange 5.5, latest sp for those versions. We're in the process of scoping out whether this can be done and have been looking through technet, Slipstick, Swynk and a few other sites but haven't really found the answer. tia for any input or guidance.
