Citrix has released a great support article on using Microsoft Lync 2010 with XenDesktop 5.5

This article contains information on using Microsoft Lync 2010 with XenDesktop 5.5.

The purpose of these tests is to assess the usability of Microsoft Lync 2010 Citrix XenDesktop 5.5 users. The tests were mainly carried out in the System 3 lab in Chalfont, but because this lab is isolated from the Citrix corporate LAN, it was necessary to use local Exchange and Lync servers, rather than Citrix corporate servers.

Because the System 3 lab is independently connected to the Internet, the Citrix Technical Support Engineers were able to include various LAN/WAN topologies during testing. The engineers were also able to simulate LAN/WAN bandwidth, latency and packet loss conditions on our networks.
