The Lync Server 2010 Resource Kit is a technical reference to Lyn Server and extends the planning, deploying and managing documentation in Microsoft’s Lync Technical Library.
After a number of months in preparation, the Lync Server 2010 Resource Kit has been published – and you can download it for free from Microsoft. The book has 18 chapters and you can download each one from the Microsoft Download Center. And from the same page, you can also get a single zip file with all the documents.
If you are interested in Lync, then these documents are a must read.
