I’m a very big fan of teams that do documentation well and update it on a regular basis. The Lync team do it well! The most recent update to the Lync help documentation was recently posted to http://www.microsoft.com/en-us/download/details.aspx?id=35405. This is a nearly 25MB file, but well worth it! This download gets a.CHM file that contains all of the available Lync S3erve 2013 IT Pro documentation in the TechNet library. Happy Days!
