I am running exchange 2007. I would like to restrict what devices are allowed to use activesync to download mail onto their mobile email client.
Example: I have an iphone 5 with activesync email setup and it works great. I get a new iphone 6. I should not be able to get activesync working on the 6 until the company has allowed this specific device.
I am not looking to block just all iphones or windows phones. I want to only allow devices that I know about whether its by mac address or serial number, etc.
