Here is the list of IP ranges that would need to be blocked on your OWA server. We have contemplated doing it several times, but have never gone through with it. If you look in your OWA logs, you'll probably notice a lot of iphone users doing the same thing.

I have considered identifying RIM's BIS IP range and blocking at the firewall level. If those IP's are only used for BIS email access and I dont want that. What about IT Policy that blocks the service book? I think that this would only block the sending but the users would end up contacting helpdesk then right? "I suddenly cant send emails any more?", "Oh you are setup with BIS!" ------------------------------------------ Josh Armour MobileOps - Sysadmin [email protected] (541) 205-4262 ------------------------------------------ On Tue, Jul 20, 2010 at 10:09 AM, Jonathan Barker <[email protected]> wrote: BIS uses IMAP and POP3. Are you sure it's turned off? Other options include offline sync using Desktop manager or a 3rd-party EAS bridge like AstraSync. From: [email protected] [mailto:[email protected]] On Behalf Of Darhl Thomason Sent: Tuesday, July 20, 2010 9:55 AM To: '[email protected]' Subject: [Bes-admins] Prevent personal Blackberries from accessing company email I just found out that we have people with personal Blackberries accessing their company email, they are definitely not set up on my BES, so I'm guessing they must be using BIS. 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!
