Blocking BlackBerry BIS from OWA

We are running Exchange 2003 and would like to block users with personal BlackBerrys from downloading their email on to their devices. I believe the ultimate fix will be to block the BIS by IP in the firewall but in the short tern we would like to block a few individuals currently using this access. I tried in AD under their personal settings to disable the Protocol Outlook Web Access under Exchange Features. This locks them out of OWA access through a browser but doesnt stop the BIS from connecting and pulling down their mail. Does anyone know if it is normal behavior for the BIS to get around this security setting and if so how it is doing it? Thanks

Hi There
you can try to disable pop and imap service for those users on the user propreties
page exchnage features.

but that will stop them from downloading email from home if the user pop or imap accounts.

POP and IMAP are disabled for all users and we don't run these services on the Exchange server. The BIS is getting in through OWA (I can see it in the logs) and OWA is enabled for all users. When I try to lock out the few users connecting through the BIS by disabling OWA for the specific user it locks them out of OWA using a browser but doesn't stop the BIS. Is it normal for the BIS to be able to connect to OWA even when the users access to OWA is disabled?
