I need to migrate a Exchange 2003 server to a new domain on another Exchange 2003 server. Will I be able to migrate the contents of the user mailbox on the old exchange sever to the new server on the new domain?

Short answer is "yes". Are the two domains in the same AD forest? if so, it is pretty easy. Just install the new Exchange server and you will be able to move the mailboxes to the new server. Tim Harrington - Catapult Systems - http://HowDoUC.blogspot.com

Hi, If it's in different forest, you have to create the trust between the forests, then use ADMT to migrate the user account, last move the contents. Thanks AllenAllen Song
