Outlook 2013 repeated reconnect attempts with Exchange 2013 or Exchange 2016 MAPI/HTTP

There are reports of performance issues and repeated reconnects when using Outlook 2013 and MAPI over HTTP in Exchange 2013. The problem is that the header that the server uses to specify the connection keep-alive period as the server is processing the request is ignored by the client. 

This is fixed in the November 2015 update for Outlook 2013, KB3101488: https://support.microsoft.com/en-us/kb/3101488.

For more information about MAPI over HTTP and how to configure it, see here.

  1. gosh, this is one more reason why users reject updates being applied. MS can't get their act together.
