I have an NT Server running Exchange 5.5 with about 250 mailboxes (Internal mail only). I will be implementing a totally new Exchange configuration on a new server which will give each user an Internet mail address which will be different from the current mail name. (Server name will be different as well). What is the best way to move all these mail boxes to the new server. All the configuration details will be different for this new server and it will not be in the same Site or organisation asthe old one.
