synchronising PST to exchange servers
 

For a number or reasons my primary calendar and mail delivery is a pst. If you have worked as a consultant roaming around the world with few opportunities to get to the mail server you will understand why.

I have trolled through a whole range of threads on the subject and just need to find a way of synchronising a PST calendar to the Exchange Server calendar so that my free/busy is up to date.

Is there a simple way to do this without reverting to the Exchange server as my primary delivery point? I am running Outlook 2010
