Lync 2013 trying to talk to Skype users using both outlook.com and msn.com are seeing this in the logs. Is this a problem at the MS side or the client side? If its a pic.lync.com problem what could it be? Federation has been enabled with the pic guys sip.clientsite.com the edge server public name is sip.clientsite.com.
