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.

A)

Directory Export all users mailbox details in csv format. Alter the csv with the new server's details and user header.exe (Microsoft Exchange Resource Kit) to create all users on new server in one hit.

This helped, the only problem was that I was using the Standard version of Exchange and most of my users had large mailboxes. So the process kept crashing. I checked the event log on W2K and realized that this was the problem, so I only brought overmail from a specific period. It worked like a charm. Thanks for your help.
