Microsoft published three sessions from the Redmond Interoperability Protocols Plugfest 2013 on Channel 9 on the protocol MAPI over HTTP or MAPI/HTTP which looks scheduled to arrive with Exchange 2013 Service Pack 1.
This protocol is set to (over time!) replace the RPC/HTTP protocol we all know. RPC/HTTP, or Outlook Anywhere, is used by Outlook to communicate with Exchange Server and is most often seen with clients working remotely. With Exchange Server 2013, support for MAPI was dropped and RPC/HTTP became the only protocol. With Exchange 2013 SP1 it seems we will receive an alternative which is set to replace RPC/HTTTP, MAPI/HTTP.
Of course, the information is preliminary and subject to change as Exchange 2013 SP1 hasn’t been released yet, but it won’t harm to get familiar with the planned changes. It also remains to be seen how quick organizations will adopt this new protocol, which I’m pretty sure we will soon see getting supported by Office 365.
