I want to signal you this project on codeplex (http://tfscollab.codeplex.com/) that contains some provider to enable collaboration with Team foundation Server power tools.

I’m expecially a fan of the Skype integration (http://blogs.msdn.com/b/bharry/archive/2013/01/14/skype-and-the-new-team-explorer.aspx) and if you use skype and TFS I strongly suggest you to give a look at that project.
