Our user gets confused asking for allow to Lync 2013 mobile client in our organization to use. However my environment using Lync Server 2010 on premises.
Resolution:
Error messaging stating that your Lync organization doesn’t support Lync 2013 Mobile client. In my case I have Lync Server 2010 and affected users are using Lync 2013 Mobile client on their mobile.
Lync server 2010 won’t support Lync 2013 Mobile client.
Because of that it shows above error shows, ‘can’t sign-in because your organization doesn’t support’.
Lync 2013 Mobile relies on Unified Communication Web API (UCWA) that comes with February 2013 Cumulative Update for Lync Server 2013 or later, which Lync Server 2010 does not provide.Lync Server 2013: If the users are signing in to an on-premises Lync Server 2013 deployment, you must apply Cumulative Update 1 for Lync Server 2013, and mobility must be enabled. For more information, go to the following Microsoft Knowledge Base article:
2809243 Updates for Lync Server 2013.The Lync 2013 Windows Phone mobile client can only be installed on Windows Phone 8 and can only connect if the user is homed on a Lync Server 2013 pool that has the cumulative update installed. If you try to sign in to a Lync Server 2010 Front End Server or a Lync Server 2013 Front End Server without the cumulative update using the Lync 2013 mobile client you will see "You can't sign in with this version of Lync.
