OVERVIEW
Teams is the chat-based workspace that brings together people, conversations and content so that teams work more effectively. You see content and chat history anytime in team chat or small group private chat, and have quick access to shared files and other content you need right in the app.
To open Microsoft Teams for the first time, you will need to have Office 365 open and you will click on the App Launcher (1). Once open, click on Teams (2). You can then pin Teams to your desktop.
With Microsoft Teams on your PC, Mac, or mobile device, you can:
Pull together a team.
Use chat instead of email.
Securely edit files at the same time.
See likes, @mentions, and replies with just a single tap.
Customize it by adding notes, web sites, and app
