Due to the email retention policies of the company I work for, I have
Outlook deliver mail to a PST so I don't lose stuff. This also
makes the calendar in my PST the default and not the one on the
Exchange server. So whenever I schedule something it does not appear
in the Exchange calendar and does not publish as free/busy.

So, is there a way I can make my default Calendar the Exchange version
& not the PST version?
