Microsoft Teams is a chat-based workspace in Office 365 that makes it easy to have conversations, share files and collaborate on documents, and get work done with teams across the organization. Microsoft Teams lets you work in a natural, conversational way — with everything you need in one place — available anytime, on any device. 

Some of the features include:

• Bring your team together as a group
• Use interactive, persistent 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, gifs and apps
• In the cloud so everyone can work together no matter where they are

A team is a group of people gathered to collaborate in your organization. Learn more about Microsoft Teams.
