Has anyone else had issues with Lync in an environment with exchange/unified communications after moving to an rMBP? Before the change Lync worked very well. Now it works fine for IM and Phone calls, but meetings.. no luck. If it does connect, it will fail after a minute or two. Definitely cannot share screens. Normally I just get a Could not connect to meeting OK/Retry screen after about 2-3 minutes. Hopefully the behavior is resolved in Mountain Lion but it is annoying as heck now. I have to grab my 13" mbp and connect to meetings that way.
