Here is my scenario: Single domain network with around 75 users running on SBS 2008 r2. The users access their email through smartphones and connect to remote.mydomain.com for authentication. We recently installed an Exchange 2010 server and so far have only moved mailboxes of a couple IT accounts which so far cannot access OWA because it hasn’t been configured yet. I’ve imported the wildcard SSL from the SBS box to the new 2010 server without too much trouble. What I would like to do is migrate everyone’s mailboxes over without having to reconfigure each user’s phones in the process. Is there a way to continue to use “remote.mydomain.com” as the OWA site on the new exchange 2010 server? And if so, will it have to be configured on the new server or will a simple http redirect work? I have some exchange experience, but very little with IIS. Thank you for being patient with me!
