So if you are reading this blog entry, the chances are that you have installed Lync for Mac 2011 and you are getting this error message:
To start, you will need to update the Software to version 14.0.1 released in October of 2011:Sign in to Microsoft Lync failed because the service is not available or you may not be connected to the Internet

Next, run Lync for Mac 2011 and on the login screen click on the "Advanced" button at the bottom of the screen, and set both the Internal and External Server links to the following:
sipdir.online.lync.com:443
That's it! This should be all you need to do to be able to use Lync on Mac OSX. Have a question or comment? Email us as support@digioz.com or post your comment here.
