These instructions are for migrating from Windows SBS 2003. If you are migrating from Windows SBS 2008, see the Microsoft Web site (

To make it easier to manually update the Outlook profiles, ensure that all users open Outlook after their mailboxes are moved to the Destination Server, while both servers are running. If both servers are running, Outlook automatically updates the profiles to point to the Destination Server. Otherwise, you must update the profiles manually to point to the Destination Server.

To migrate Exchange Server 2003 mailboxes

  1. On the Destination Server, click Start, click All Programs, click Microsoft Exchange Server 2007, and then click Exchange Management Console.

  2. Click Continue on the User Account Control dialog box.

  3. In the Exchange Management Console navigation pane, expand the Recipient Configuration node, and then click Mailbox.

  4. In the results pane, select all of the legacy mailboxes, and then click Move Mailbox in the task pane. The Move Mailbox Wizard starts.

    Legacy mailboxes are identified in the Recipient Type Details column.

  5. In the Move Mailbox Wizard, do the following:

    1. On the Introduction page, click Browse, click the Windows SBS 2008 mailbox database, click OK, and then click Next.

    2. On the Move Options page, click Skip the corrupted messages, and set the maximum number of corrupted messages to skip.

      If mailboxes are skipped because the maximum number of corrupted messages is exceeded, either delete those mailboxes or run the Move Mailbox Wizard again before you uninstall Exchange Server 2003 later in the migration.

    3. Select the Active Directory servers, and then click Next.

    4. On the Move Schedule page, select when you want to move the mailboxes, and then click Next.

    5. On the Move Mailbox page, review the mailboxes that will be moved, and then click Move.

    6. Click Finish.

  6. Verify that there are no more legacy mailboxes listed in the details pane of the Exchange Management Console, and then close the console.
