Lync 2013 server, Lync 2013 client.
When client connects outside LAN thru EDGE after he sign in he immediately get a pop-up window for credentials.
No matter if the credentials are put right, after puting those credentials into the form the window just reopens it.
Users solves this problem by clicking cancel.
After clicking cancel and some seconds later a Microsoft Outlook credential pop-up window appears.
If the client puts the credentials there that window dissapear.
Any clue how to solve this?
We have already recreated kerberos account for lync but that did not do any good.

We also use TMG as single network adapter. We use it only for reverse proxy.
Please advise
