Hi,

We have a standard lync server and an edge one. Few weeks ago, the federation with all our parteners was working fine. But now, it doesn't.

When i run the logger on the edge server and i try to add a new contact (federated contact) these messages are recorded and the contact status still in the unknown presence.
