The Exchange Management Console includes a Move Mailbox wizard to migrate user mailboxes from an Exchange 2003 server to a new Exchange Server 2007 Mailbox server.

Before moving any mailbox you should make sure you configure the Mailbox server, configure the Client Access server and migrate Outlook Web Access, and export a list of SMTP addresses for your users.

Launch the Exchange Management Console and navigate to Recipient Configuration/Mailbox.  Each of the existing mailbox users in the organization will be visible as a “Legacy Mailbox”.

Mailbox can be moved individually or in batches.  Before you begin you may want to think about whether to enable circular logging to prevent transaction logging during the migration from filling up your disks.  If you don’t want to move all of the mailboxes at once you can migrate in batches instead.

Select the mailboxes you want to move.  Right-click the selection and choose Move Mailbox…
