Export-Mailbox -Identity user@domain.com -PSTFolderPath "e:\pstfiles" -Confirm: $false results in the following error statement: Export-Mailbox : Error was found for <user user@domain.com> because: Error occurred in the step: Approving object. An unknown error has occurred., error code: -2147221233At line:1 char:15+ Export-Mailbox <<<< -Identity user@domain.com -PSTFolderPath "e:\pstfiles" -Confirm: $false The subsequent info dump contains: StatusCode : -2147221233StatusMessage : Error occurred in the step: Approving object. An unknown error has occurred. I suspect this is a permissions issue. I subsequently explicitly allowed the Administrator account Full Access to the target mailbox, with the same results. I'm stumped. Anyone have a clue??

I would confirm the account has all the necessary permissions required for export-mailbox. http://technet.microsoft.com/en-us/library/aa998579.aspx Exchange Server Administrator role and local Administrators group for the target server Full access to the source and target mailboxes I would also use a non-admin level account, and ensure it has SEND AS and RECEIVE AS perms on that mailbox. Then test.
