Note:
While the Exchange clients are not required to be disconnected from their mailboxes during a move mailbox operation, it is recommended that the move take place when Exchange client activity is low, such as off peak hours, to avoid possible service disruption.

  4. Right-click the selected users, and then click Exchange Tasks.

  5. In the Exchange Task Wizard, click Next.

  6. On the Available Tasks page, click Move Mailbox under Select a task to perform, and then click Next.

  7. On the Move Mailbox page, in the Server list, click the server you want, and then, in the Mailbox Store list, click the mailbox store you want.

  8. Click Next.

  9. Configure how you want any corrupted messages that are found during the move to be handled, and then click Next.
