As the question says, what protocol does Windows Phone (and similar platforms) use to connect to mobile only exchange servers, such as m.google.com?
回答1:
It uses the Exchange ActiveSync protocol, documented here. (Note that as it's a protocol, that means it doesn't actually have to talk to Exchange servers... just servers which speak the same protocol.)
(As an aside, the quality of client support for this protocol is, um, variable. Some phones have a very interesting idea of what constitutes valid time zone information.)
