Exporting a Mailbox to PST on Exchange x64

Strangely, you cannot run the Export-Mailbox command on a 64-bit version of Exchange Server 2007 in order to export a mailbox to a PST file.

Instead you need to
  • create a 32-bit VM (say Windows XP 32 bit)
  • Join that machine to your domain
  • install Outlook (32-bit) onto it
  • Install IIS Common Files from Add Or Remove Windows Components
  • download and install the Exchange Management Tools for 32-bit
  • Login as Domain Admin
then run the Export-Mailbox command from the Exchange Management Shell.

export-mailbox -identity <user> -PSTFolderPath c:\backup\<filename>.pst

This then fails with

Are you sure you want to perform this action?
Exporting mailbox content from the mailbox '<User>' into .pst file
<filename>.pst'. This operation may take a long time to complete.

This is because the running user does not have permission to access the mailbox.


Get-Mailbox | Add-MailboxPermission -User "<YourUserName>" -AccessRights FullAccess
and repeat

export-mailbox -identity <user> -PSTFolderPath c:\backup\<filename>.pst
