In this video, learn how to plan for MAPI over HTTP and Outlook Anywhere. MoH and OA are features that allow Outlook and mobile users to connect to the Exchange server using certificate-based security while away from the office. OA is being replaced by MAPI over HTTP, but OA can still be accessed by older Outlook versions and other clients.
- [Instructor] Over the years, there's been many ways Outlook users could connect to Exchange without being on the local area network. Up until Exchange Server 2010, we used RPC over HTTP. This was followed by the more secure Outlook Anywhere that worked up until Exchange Server 2016. In 2019, however, we mainly used MAPI over HTTP. Messaging Application Programming Interface, or MAPI, over HTTP is a transport protocol that improves the reliability and stability of the Outlook and Exchange connections by moving the transport layer to the industry standard HTTP model. This allows for a higher level of visibility of transport errors and enhanced recoverability. Using MAPI over HTTP in Outlook requires a certain version, we need to be on at least Outlook 2013 SP1 or newer. So that also includes 2016 and 2019. In order to make MAPI over HTTP work, we have to use a certain type of certificate, called a SAN certificate. And if we take a look at the old way of doing things, when we used a SAN certificate, it included the internal name and external name. Over the years, however, Microsoft has determined that it's not a secure thing to have the internal Active Directory domain name in the certificate, so they changed it to require a SAN certificate using just the external name with the internal and external host addresses. By hiding the Active Directory domain name, you reduce the possibility that a hacker could gain access to the system. In an upcoming video, we will demonstrate how to configure MAPI over HTTP and we will also demonstrate the purchase of a SAN certificate and installing that certificate into Exchange Server 2019. MAPI over HTTP is a secure, reliable protocol for connecting Outlook clients to Exchange Server 2019, even while away from the office.
