Lync course questions, answers and links

I have enjoyed training people on Lync 2013 for about one and a half years by now, and Lync 2010 before that. I would like to thank all my students for their participation in the courses, all the questions, comments and ideas have really got me thinking and working. So far I have met some 150 students in Sweden and around 50 international English speaking students. I will probably run a couple of more Lync 2013 classes, but currently I am really focusing on the forthcoming Skype for business software (aka Lync 2015). (Anyone need a Skype for Business trainer?)

Hence I would like to post a concluding Lync 2013 information article. Basically it is some of the questions I received from students, many of them asked more than once, and also a lot of links pointing to solid Lync 2013 information. Enjoy!
