  • You have a computer that has Outlook 2003 (SP2) or 2007, Exchange 2007 Management Tools (32-bit version), PowerShell and .NET Framework installed
  • Logon with an account that has Exchange Server Administrator and Local Administrator rights
  • You have full access to the users’ mailbox on both servers. See the note below on how to do it.


    1. Start the Exchange Management Shell and type the following:[PS] C:\>Get-Mailbox –Database “<Exchange Server FQDN>\<Database Name>” | Export-Mailbox –PSTFolderPath C:\PSTFiles to export all users mailbox to a PST file. Press A for Yes to All. Depending on the size of your database, the export procedure could take a long time to complete.
    2. Now the mailboxes are exported to the PST files, make sure that the PST file name matches the alias of the users’ account in the other domain.
    3. Next, import the PST files to the other Exchange Server by typing the following: [PS] C:\>Get-Mailbox –Database “<Exchange Server FQDN>\<Database Name>” | Import-Mailbox –PSTFolderPath C:\PSTFiles and press A for Yes for All. Wait until the import operation completes.

    [PS] C:\>Get-Mailbox -Database “<Exchange Server FQDN>\<Database Name>” | Add-ADPermission -User Administrator -AccessRights GenericAll
