Explanation:
The Microsoft Connectivity Analyzer (MCA) tool is a companion to the Microsoft Remote Connectivity Analyzer web site. The MCA tool provides administrators and endusers with the ability to run connectivity diagnostics for five common connectivity symptoms directly from their local computer. One of the five symptoms that can be tested using MCA is:
“I can’t log on to Lync on my mobile device or the Lync Windows Store App” – This test checks for the Domain Name Server (DNS) records for your on- premise domain to ensure they are configured correctly for supporting Mobile Lync clients. Also it connects to the Autodiscover web service and makes sure that the authentication, certificate, web service for Mobility is correctly set up.
