I need to change the Authoritative SMTP to domain mydomain2.com (existing is mydomain1.com and will be kept as a secondary). I am fine with the steps to do this in exchange 2010 however my confusion is with my current ssl certificate for mydomain1.com. If I keep dns pointers (active sync and owa) as mail.mydomain1.com...
1. will users till be able to access their mailboxes?
2. do I need a second SSL cert to satisfy the mydomain2.com if users are still using the primary mail.mydomain2.com addresses to reach active sync / OWA
3. If I use the mydomain1.com address for remote access...will I need to make IIS changes.
My goal was to implement the new mydomain2.com as the primary for immediate public visibility in regards to email reply to and then phase II the change of SSL cert and IIS (if needed). Or am I being Naïve?
The server domain of internal.local remains the same.
