We are trying to lockdown access to email through the BES server ONLY (and Outlook
no OWA or OMA either). As such, I am trying to identify all the possible points of access and means of preventing access whether Blackberry based or not.
1. Active Sync - Can disable in Exchange
2. BIS (user enters SMTP server info) - Can this be disabled? Set of IP addresses to be blocked?
3. Exchange Redirector - BB Desktop software with USB. I haven't used this in a while, but there really doesn't seem to be a way to stop it. Maybe set a registry key??
Any other thoughts?
