Windows Store Lync App

Microsoft recently released a version of the Lync client for Windows 8 and Windows tablets such as the new Microsoft Surface.  The new client version is officially called “Windows Store Lync App” (a.k.a. Lync MX, Lync RT, Win 8 Lync App, and Lync Metro). This version is optimized for touchscreen and runs on any flavor of Windows 8.  It does not run on Windows 7. The Windows Store Lync App can connect to Lync Sever 2010, Lync Server 2013, and Lync Online in Office 365
