You get everything you need for conversations in one app—IM, audio and video calls, online meetings and sharing. It’s simple to collaborate right from your Office apps. You’ll see the contact card of everyone working in the same app as you so you can quickly send them an IM or email, or start a call. You can also schedule meetings and see IM history in Outlook, and start meetings from apps like Word and PowerPoint to present whatever you’re working on.

Reach out to anyone in your company, or to the hundreds of millions of people on Skype, on your favorite device or web browser. Even if they’re not on Skype for Business, up to 250 people can join meetings—all they need is a landline phone or Internet connection.
