How do I un-archive from enterprise vault and store all my old emails to a
PST folder?

I can't help with Enterprise Vault, since I don't know what it is, but I can
suggest that you should keep your Exchange mailbox as the delivery location
and create a rule that will move anything using the form "Message" to a PST.
That way, only mail will get transferred to the PST. The rest will stay in
the mailbox.
