About the App

• However, I do not have Skype for Business and the MS website appears to be asking me to download something called Lync, but I can only find updates for Lync, not an original download. The version of Office for Mac 2011 I have does not contain Lync, so don't have an earlier version I can update.
• Microsoft Lync for Mac gives you instant messaging (IM), audio and video calls, online meetings, availability (presence) information, and sharing capabilities all from one, easy-to-use program.It’s a slimmer version of the full Lync client and provides the same core functionality. Microsoft Lync for macOS is the new rich client for Lync users on the Mac platform and offers integrated.
• Lync Web App is the browser-based version of Lync 2010 that allows people who don’t have a Lync account and haven’t installed the Lync client to participate in Lync meetings, using either a Windows or Macintosh operating system.
• Notes: Unlike other Mac applications, you cannot add custom emoticons or emoticons from other applications to Lync for Mac. For a list of more emoticons that you can use in Lync for Mac, see the article Keyboard shortcuts for emoticons. To turn off emoticons, on the Lync menu, click Preferences Appearance.Under Emoticons, clear the Show emoticons in instant messages check box.
