when i saw this video is available at TechEd for Lync edge Servers and speaker is Dr.Rez,i havent for a second a started streaming this video, but when start watching it i was so much disappointed its wasn't Dr.Rez, and not only this, that Speaker is also wasn't technical enough to talk about Lync queries about Edge server. He was too much confused many times, he was unable to reply to some valuable question being asked by audience, a very much irresponsible presentation for a very very very sensitive LYNC 2010 topic .. Microsoft please kindly let Dr.Rez define the same presentation and upload that video, Really i found this video unfocused.Just the Q & A session part conducted by another speaker which was some informative but i expect Dr.Rez.. is Dr.Rezz.. i love his blog.. he knows what LYNC actually is!!!
