BES is outbound - just don't block outbound and you're fine. You're blocking inbound for OWA/BIS, which is what he said in an earlier post.

Is there another list that shows the BES IP's? I'd want to make sure that they were allowed, the ranges provided for BIS are pretty large and I wouldn't be surprised if they overlap to some degree.

See: http://www.port3101.org/featured-blackberry-kb-articles/792-kb11036-fire wall-connection-requirements-blackberry-internet-service.html for a list of what IP's BIS connections are coming from. Block these inbound connections at the firewall and you've blocked BIS.

Are you sure it's turned off? Other options include offline sync using Desktop manager or a 3rd-party EAS bridge like AstraSync.

How can I prevent them from accessing their company email on their personal devices? I know it's not via IMAP or POP3, we have that turned off at the Exchange level. Thanks!
