BIS can also use OWA. See: http://www.port3101.org/featured-blackberry-kb-articles/792-kb11036-firewall-connection-requirements-blackberry-internet-service.htm l 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!
