A technical deep dive into MAPI/HTTP and its effect on Office 365 performance

On October 31st, Microsoft stopped supporting the RPC/HTTP protocol and required switching to another protocol, called MAPI/HTTP. The MAPI/HTTP protocol was created in 2014, so while it isn’t entirely new, this is the first time it’s becoming required.

Switching to MAPI protocol isn’t technologically difficult, but it does require a lot of work and strict adherence to Microsoft’s guidelines.

People are understandably concerned about the switch, partly because companies who have already made the switch have seen an increase in the number of performance tickets.

In this technical podcast, GSX experts will help you understand how the MAPI/HTTP protocol impacts Office 365 performance, and how performance issues may arise from equipment that is not compatible with this protocol.
