Client version configuration settings are used to turn client version control on or off, either globally or for particular sites. The global client version configuration installs with Lync Server 2013 and is used to enable or disable client version control for the entire server deployment. When the global configuration is enabled, any client version policies you have in place will take effect when users attempt to log on. You can disable the global client version configuration if you do not want any client version control to occur. You can enable or disable client versioning from Lync Server 2013 Control Panel or Lync Server 2013 Management Shell.

Because anonymous users are not associated with a user, site, or service, anonymous users are affected by global-level policies only.

To enable or disable client versioning by using Lync Server Control Panel

  1. From a user account that is assigned to the CsUserAdministrator role or the CsAdministrator role, log on to any computer in your internal deployment.

  2. Open a browser window, and then enter the Admin URL to open the Lync Server Control Panel. For details about the different methods you can use to start Lync Server Control Panel, see Open Lync Server Administrative Tools.

  3. In the left navigation bar, click Clients, and then click the Client Version Configuration navigation button.

  4. Do the following:

    • To globally enable or disable client versioning, double-click the Global configuration, and then modify the settings.

    • To enable or disable client versioning for a particular site, click New, select the site, click OK, and then modify the settings for the site.

Enabling or Disabling Client Versioning by Using Windows PowerShell Cmdlets

You can enable or disable client versioning by using the Set-CsClientVersionConfiguration cmdlet. This cmdlet can be run either from the Lync Server 2013 Management Shell or from a remote session of Windows PowerShell. For details about using remote Windows PowerShell to connect to Lync Server, see the Lync Server Windows PowerShell blog article "Quick Start: Managing Microsoft Lync Server 2010 Using Remote PowerShell" at
