MAPI over HTTP in Exchange 2016

MAPI over HTTP is presently the default protocol that Outlook uses to communicate with Exchange. MAPI over HTTP enhances the stability and reliability of the Outlook and Exchange connections by shifting the transport layer as per the industry-standard HTTP model.
This permits a higher level of availability and visibility of transport errors and improved recoverability. Additional functionality consists of support for an explicit pause-and-resume feature that enables supported clients to alter networks or continue from hibernation while maintaining the same server context.

Kindly Note:

MAPI over HTTP isn’t enabled in organizations where the following given conditions are set to be true:

  •  An organization which has already installed Exchange 2013 servers and you’re installing Exchange 2016.
  •  MAPI over HTTP is not enabled in Exchange 2013.

While MAPI over HTTP is now the default communication protocol between Outlook and Exchange, clients which don’t help and support it is going to fall back to Outlook Anywhere (RPC over HTTP).
