Microsoft Lync is a unified messaging software for the corporate environment built by Microsoft. In addition to standard chat messages, Microsoft Lync also supports video conferences and phone calls. It’s worth mentioning that Lync syncs with Microsoft Outlook and your calendar allowing you to set your online presence based on your calendar schedule.
Despite its usefulness, Microsoft Lync was replaced by Skype for Business, but the basic version of Lync is still available. This version is a slimmed version of Lync 2013, so it supports the same core features. Those features include a clean look, favorites, several different display options for your contacts, tabbed conversations, persistent chat rooms, topic feeds and much more.
