I currently have a single public IP tied into mail.company.com on the SMTP Virtual server in my Exchange 2003 server. Users currently use OWA by going to https://mail.company.com/exchange
I have installed a Exchange 2010 server and used name.company.com during the install process and it is setup on both the internal and external https address for OWA in exchange 2010.
I have migrated only my mailbox over to 2010 and mail flow works internally/externally but naturally the OWA will not work since I don't have a 2nd IP and DNS A record.
If I migrate everyone over can I just change the URL's on exchange 2010 from name.company.com to mail.company.com and just do another self signed cert? If not what is the normal process to get OWA working after a migration?
