Currrently, we have one public ip address linked to one exchange server for OWA access which works great. Now, the problem that I am trying to resolve is having that one ip address being able to connect to 4 other exchange servers on the network. All them are able to communcate with one another.
now, what I did notice was that I was able to get OMA working through connecting to the one public ip address exchange server to a user on a different exchange server.
also.. we are running exchange 2003 enterprise.
