I am in the process of migrating mailboxes from a 2003 exchange to a 2007.
so fareverything works fine, mailboxes get copied, mail flows, clients update their info after the move, everything looks ok
my only problem right now is that, when a user whose mailbox is stil on the 2003 server tries the external url https://server.domain.gr/exchange
he gets redirected to the internal ip address of the 2003 server, which, of course, won't work outside our LAN.
how do I get OWA 2007 to redirect legacy mailbox users to the public address of the 2003 server?
