Lync Web App Supported Platforms

Topic Last Modified: 2011-07-15

To use Microsoft Lync Web App, you must have one of the following supported operating system and browser combinations.

Note:
The Microsoft Silverlight browser plug-in version 4.0 must be installed on your computer. The sharing feature requires a plug-in. The first time users initiate a sharing session, they will be prompted to download the required sharing plug-in. Because the Microsoft Silverlight browser plug-in is not supported on 64-bit browsers, Lync Web App is not supported on 64-bit browsers. The exception is the 64-bit version of Safari running on the Macintosh operating system; the 64-bit version of Safari allows the Microsoft Silverlight browser plug-in to run in 32-bit mode and is therefore supported. The sharing feature is available to Windows users. Users of Macintosh operating systems can view shared content but cannot initiate sharing.
