What is Skype for Business?
Skype for Business is a communications and collaboration platform that brings together an experience inspired by Skype with enterprise-grade security, compliance and control. It offers features including presence, IM, voice and video calls, and online meetings. It is built right in to Microsoft Office, so initiating chats, calls and meetings is an integrated experience within Office.
