How can we move mailbox-enabled user accounts from one Windows 2000 domain to another domain while at the same time preserving these users' mailbox data?
The procedure for moving mailbox-enabled accounts from one domain to another is surprisingly simple. To move the accounts, just perform the following steps:
- Back up the user's mailbox by exporting it to a personal folder store (PST) file (this is a just-in-case step, but skip it at your peril).
- Use the Exchange System Manager (ESM) tool to move the mailbox to the destination Exchange 2000 Server machine.
- Use movetree.exe (from the Win2K Support Tools) to move the user object from Domain1 to Domain2.
