The BB10 device is using Active Sync to communicate with the Exchange Server, do the messages route through the BES10 server or do they communicate directly with Exchange just as other Active Sync connections i.e. iOS and Android. Is the primary role of the BES10 to push IT policy and applications, and leave the messaging alone?
The question stems from our deployment of the BES10 and the high utilization of our CAS servers, in front of our Exchange machines. It could be a coincident, but I would like to rule this out before I turn the BES10 back on.

The actual connection isn't between the Z10 and ActiveSync. BDS proxies Exchange through ActiveSync, the message comes back to BDS were it's re-encapsulated to 256bit AES/3DES, it then tired to BBRY NOC and from there it's sent to the device, this is how it works for BB10 devices and your Playbook.
The other reason why you are wrong if you read the documentation you would know that your Exchange server doesn't need to be open to the internet for BDS. So go try it...turn off your HTTP/S traffice to your Exchange and see if your emails still works...I bet you it does! I know it does becuase I don't have my Exchange open to the internet, os no OWA or anything is open on the outside.
iOS and Android devices grab emais directly from your Exchange server on the internet through ActiveSync.

I think this needs to be emphasized MUCH BETTER
Many service vendors are saying that the new handsets are not using the Blackberry infrastructure just directly ActiveSync like iPhone and Android.... My vendor used this argument to try to get us drop BB

Okay so your not confursed BB10 devices used BDS.
