Microsoft Communicator 2011 allows Mac users to communicate and collaborate with Office Windows users and of course features complete integration with Microsoft Outlook (now available for Mac) and every other component of Microsoft Office for Mac 2011. This is a big advantage over Microsoft Messenger which is 'closed' to protocols other than Microsoft Messenger. Not only that, thanks to Microsoft Communications Server or Lync (the hardware infrastructure needed to use Communicator) it can support multiple IM protocols meaning you can communicate with those using Windows Live Chat, Yahoo and Jabber. Microsoft Communicator 2011 can handle everything from instant messaging to telephony, video chatting and teleconferencing.
