:exchange2007 – Exporting all mailboxes to .PST
Recently I tasked with exporting all mailboxes on an Exchange 2007 server to PST files during a migration from one company to another. These are completely separate forests and for whatever reason they did not want a trust set up between the two to do this.
I decided to go with the Export-Mailbox cmdlet within the Exchange Management Shell to achieve this, but it turns out there are a couple of hoops I had to jump through before being able to do this.
