Answer 1

looks like a permission issue

In the Exchange Management Console, under the Server Configuration node, select Hub Transport and the name of the server. In the Receive Connectors pane, open either of the Recive Connectors (my default installation created 2) or you can create a new one just for TFS (I also tried this and it worked). For any of these connectors, open Properties and on the Permission Groups tab ensure that Anonymous Users is selected (it's not by default).
