I have a user that needs to do the following. Receive emails from Exchange from Company A which is using an SBS Server. And the blackberry needs to be on a BES from a Company B. I understand a blackberry can't be setup on two BES's. So I need to know how to configure the Exchange on Company A so they can get their email without. It has to be setup so that Company B is pushing emails to the blackberry via BES and Company A is allow the blackberry to connect to the exchange another way to get the mail.
