    Automatic discovery of the Lync server failed. Please verify the server requirements at http://go.microsoft.com/fwlink/?LinkId=278998 . Lync mobile apps do not require automatic discovery. You could enter the server FQDN manually and test connectivity again.

    Microsoft Lync Connectivity Analyzer cannot analyze deployment readiness until a discovery test has completed successfully.
