We currently have an issue where there are multiple people using the OWA address to connect their personal blackberries to our exchange server. We run a BES server and issue blackberries to authorized people, but need to block unauthorized access by these other blackberries. Blackberry's support has said the only way is to turn OWA off for the people you don't want to have access. Unfortunately, this is not a solution as we allow people access to OWA.Does anyone know how to block these unauthorized blackberries from making connection?Thanks,Mike

If they are using the OWA address to configure BB that means they are using the active sync. Basically in BES you need to add their account on BES server in order to access emails. Disable the active sync feature for these users Vinod |CCNA|MCSE 2003 +Messaging|MCTS|ITIL V3|
