Hi, I need to get some form of interoffice chat feature and online collaboration capability established. It looks like the Lync product can achieve this, but I am a total newbie to Lync. I have an Exchange 2007 server environment and we are running Office 2010 on the desktops. I'm assuming that I would need to create a Lync server ... any recommendations on the OS (8 or 12). Would I need to upgrade the Exchange server (that is one of my upcoming projects, but not quite ready yet)? If you have any "getting started" or other training links that you can share, that would be awesome. Thanks in advance for the advise.
