It is well documented that you can have a Lync file share on a DFS share. You can read about that right here. But what is missing in that documentation is the syntax for creating the file store in the Lync Topology Builder. As many times as I have done this task, I always forget. Then I have to work my way through it and figure out the syntax. And the documentation does not help when it comes to the Lync. Well, no more.
