Lync 2011 Sign-in Issues So on my windows laptop, Lync 2013 is set to automatically configure the connection settings, however when I try to automatically configure the connection settings on my mac it doesn't work.

Is there any way to get the automatic connection settings from my windows laptop so that I can set them manually on my mac?
I just downloaded Lync from Office 365 and had the exact same problem. After a bit of googling I realised that my Lync version was 14.01 and there was an update to 14.09 available. Updating solved my log in problem. Very simple (And stupid: 1. Why does Microsoft not update the package at Office 365? 2. How can login be broken to start with?).
