Is there a way to block outlook web access from non-trusted browsers? For example: someone with a blackberry device can connect to OWA and view email, however the email is cached.. This device connects to OWA instead of Activesync and therefore does not have device policies applied (which means no-remote wipe if it is lost/stolen). I would like to prevent the device from connecting via OWA based upon the browser header (I know its not perfect, but a blackberry user shouldnt be able to modify the header). I've had to disable OWA for certain users because of this type of misuse however I would like to give them the option for accessing OWA from IE/Firefox, just not with their blackberry handheld (any authorized blackberry would be using BES to synchronize mail, never OWA). Thanks in advance

This is not something that is built-in to Exchange. What you are asking for is browser sniffing, so that would have to be handled at the reverse proxy/ content filtering level outside of Exchange. Note that since any browser can be mimicked through extensions or code, its not a very effective way to handle this. Whats the difference between caching web data on a blackberry versus on my home laptop?
