Deploying Lync Web App

Topic Last Modified: 2011-01-26

Microsoft Lync Web App is an Internet Information Services (IIS) web client that installs with Microsoft Lync Server 2010 and is enabled by default. No additional steps are necessary to either enable Lync Web App on the server or deploy the web client to users. When users click a meeting URL, they are presented with the meeting join page, which provides the option to join the meeting by using Lync Web App.

Your main consideration during client deployment is whether to install the following software prerequisites for Lync Web App in advance or to allow users to install them as needed:

• The Microsoft Silverlight 4.0 browser plug-in is required for Lync Web App. You can deploy Silverlight 4.0 to client computers, or you can allow users to be prompted for installation when they first start Lync Web App.

• The sharing feature in Lync Web App requires a Microsoft ActiveX control. The first time users initiate a sharing session, they will be prompted to download the required ActiveX control.
