LoadGen 2013 MAPI over HTTP support?

Hello,

Can LoadGen 2013 (15.0.85.0 dated 10/11/2013) be made to use the Mapi over Http transport in Exchange 2013 SP1 and greater? If not, any plans for future support?

I've enabled MAPI over HTTP for the organization in my test network, and am watching PerfMon counters from the MsExchange MapiHttp EmsMdb and MsExchange RpcClientAcccess counter sets. I've been unable to find any combination of parameters in the test configuration file that result in the loadgen requests being handled in Mapi over Http.

Thanks,

John Lowery
