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

Note:
  • 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 computer users. Macintosh computer users can view shared content but cannot initiate sharing.
