Outlook Anywhere also essentially double wrapped all of the communications with Exchange adding to the complexity. MAPI/HTTP will generate a maximum of 2 current connections generating one long lived connection and an additional on-demand short-lived connection. This change will reduce the number of concurrent TCP connections established between the client and server. Gone are the twin RPC_DATA_IN and RPC_DATA_OUT connections required in the past for each RPC/HTTP session. MAPI/HTTP moves connectivity to a true HTTP request/response pattern and no longer requires two long-lived TCP connections to be open for each session between Outlook and Exchange. MAPI/HTTP removes the complexity of Outlook Anywhere’s dependency on the legacy RPC technology. It is the long term replacement for RPC over HTTP connectivity (commonly referred to as Outlook Anywhere). MAPI/HTTP was first delivered with Exchange 2013 SP1 and Outlook 2013 SP1 and begins gradually rolling out in Office 365 in May. MAPI over HTTP is a new transport used to connect Outlook and Exchange.
