Migration of Users to Different Exchange 2003 Server in Different Domain
I am looking to move all (10) accounts off of a 2003 Exchange Server on domain abc.com to a different 2003 Exchage server on domain def.com. I have copied the user mailboxes to the different Exchange Server on def.com. Domains abc.com and def.com are completely independent. I have the following questions:
(1) What has to be changed so that emails addressed to email@example.com come to the different Exchange server in domain def.com?
(2) How can I allow these 10 users to keep their email addresses (for example firstname.lastname@example.org) and have any email send to email@example.com come directly to their new mailbox on the different Exchange Server on domain def.com?
(3) How can I set it up so that emails coming from johndoe on the different Exchange server in domain def.com still appear to be coming from firstname.lastname@example.org?
