I am trying to explore if MAPI can work with HTTP/2. And since HTTP is just a transport wrapper on top of MAPI, I believe it should have no problem working with HTTP/2 as well.
While checking the exchange online(outlook.office365.com) I found that it is still using HTTP1.1 even though the server is Microsoft-IIS/10.0 which supports HTTP/2.
Now I want to understand if MAPI over HTTP2 is possible? If yes, why is it not enabled for outlook.office365.com?
