Move Mailboxes from Exchange 2010 Servers to Exchange 2003 Servers

  • Article

Applies to: Exchange Server 2010

Moving mailboxes from Microsoft Exchange Server 2010 to Exchange Server 2003? Consider the following:

  • The move process is performed offline, and end-users won't be able to access their mailboxes during the move.
  • Perform the move from the server running Exchange 2010 by using the move request cmdlets in the Exchange Management Shell. You can't use Exchange System Manager on an Exchange 2003 server to move the mailboxes.
  • If you're moving a mailbox that has a personal archive associated with it, you must disable the archive before moving the mailbox. For details, see Disable a Personal Archive for a Mailbox.
