in my job as a PFE I spend a lot of time teaching workshops on a variety of Lync components. One of the resources I generally hand out when students complete the course is a big list of resources I recommend they have a look at to help them on their journey to obtaining Lync masterdom. I am still on the journey, but these resources have definitely helped me out along the way. So well, I just had to share them.
I put together a Lync Online/Office 365 list of resources here http://blogs.msdn.com/b/canberrapfe/archive/2014/06/19/if-you-re-looking-to-ramp-on-lync-online-and-office365-here-are-some-useful-resources-well-worth-a-visit.aspx.
