Existing Exchange server migrating new Domain RRS feed

  • E-mail addresses don't have anything to do with your AD domain name.  Just add the new domain as an accepted domain, add e-mail addresses to recipient objects (which you can automate to a large extent through e-mail address policy), and then add the new MX record pointing to Exchange.  There may be more to do based on your own particular environment.

  • That isn't something you need to worry about.  The e-mail stays fine if you follow the advice I gave you.
