This 17 page document was republished this February 2012 (originally published April 2011) to account for changes in the Lync 2010 product.
This document describes the supported functionality, environments, tools, limitations, and outlines a series of best practice recommendations for running the Microsoft® Lync™ 2010 communications software client in a virtualized environment. For capabilities that are supported across different architectures, see the “Supported Functionality” section later in this document.
This document does not cover scale requirements and recommendations thereof. This is because scale requirements for a given enterprise depend on enterprise applications that must reside alongside Lync 2010 and would need to be identified on a case-by-case basis.
