I have approx 30 Blackberry Cell Phone users and Exchange 2003 back end. Each person needs to have 2 address books available on their phone synced with Exchange. The first one is the ones that the user updates. The second one will be managed internally and "pushed" to all Blackberries. Currently I do not have a BES server. Can this be done without one. If so how? If not, can it be done with a BES?
