How can I change which AD account an Exchange mailbox is connected to without deleting the account?

  • 772

I would like to move an Exchange 2010 mailbox from mydomain\userAccount1 to mydomain\userAccount2 without deleting userAccount1.

I have seen numerous articles online that talk about how to do this after userAccount1 is deleted but none that provide steps to move a mailbox with all its e-mail, active sync relationships, and other metadata over to a different active directory user account.

How can I move a mailbox from mydomain\userAccount1 to mydomain\userAccount2 without deleting userAccount1?

    You may try to performs these steps:

    1. removing Exchange attributes for userAccount1 using the Disable-Mailbox cmdlet
    2. running Clean-MailboxDatabase
    3. reconnecting the mailbox to userAccount2 using the Connect-Mailbox cmdlet

    Hope this helps.

  3. Maxwells answer dated 2012/05/02 @ 14:09 is correct.

    Quoted directly from the 'Disable-Mailbox' online link:

    The Disable-Mailbox cmdlet removes the mailbox's Exchange attributes from Active Directory. The mailbox isn't deleted and can be reconnected to its user at a later date by using the Connect-Mailbox cmdlet.
