Lync MAPI Connectivity Into Exchange (UcMAPI.exe)

It does. Authentication initiated through both the Outlook client and Lync's UcMAPI.exe process both seem to throw the errors into the APM log as they are both initiating connectivity to APM with a HTTP method of RPC_OUT_DATA. However, the session successfully passes Policy Evaluation and holds consistently throughout the entire usage of either client. All in all, this appears to be more of a cosmetic concern than anything functional.

On another note, we JUST upgraded to 11.5.3 HF2, so I'm wondering if we may be seeing some fallout from a recent bug fix. Perhaps this may not be related to the Exchange Profile/iApp and it could be a new finding.

I will continue to poke around today and see if I can find anything else.
