Hello ! We are to change our email domain address from @domain1.com to @domain2.com. We use Exchange 2007 SP2. We added the field to each email accounts and put the new domain (domain2.com) as default.We will clearly keep the old domain (domain1.com) but a desire of management is to annonce the name change. Is there a way to automatically reply to email that is sent to the domain1.com letting them know that our email domain has changed to domain1.com so they can change their records? So just an auto reply for the domain1.com. just an auto reply for the alias of domain1.com. It would be nice to do this from the server so the users don't have to worry about it. Thanks for your reply
