exchange protocols - MAPI, MAPI over HTTP, outlook anywhere. what are the differences? RRS feed

  • Question

  • Hi.

    I am completely confused- I am trying to understand the differences between MAPI, MAPI over HTTP, and outlook anywhere. From this article: https://technet.microsoft.com/en-us/library/dn635177(v=exchg.150).aspx it seems that exchange uses RPC directly with outlook clients.

    they all seem to involve RPC (my understanding is that MAPI is even running on the same ports as RPC), but I can't understand the differences between them, why the need to switch protocols, and what is was used when (in what version of exchange)

    A short 'for dummies' explanation will be greatly appreciated

    Outlook Anywhere is a service provided by the Client Access server role that allows Outlook clients to make a secure connection over SSL/HTTPS to the mailbox from remote locations. Previously this was known as RPC-over-HTTPS but was renamed to Outlook Anywhere in Exchange 2007 and 2010.
