The app offers a variety of ways to communicate: chat, audio-only, and video.

Teams lets you chat via text, audio, or video.

The page will list people or groups of people you've recently chatted with; select one to start a new conversation.

(You can allow Teams to access your contacts to make things a bit easier.) You can also start a group chat with up to 20 people and name the group for use again.

Once you’ve identified the person or persons you want to chat with, select “Send invite.” They’ll get a notice that you’re starting a chat, and they’ll be invited to download Teams (assuming they haven’t done so already).

Above the chat area, video and phone icons let you turn the chat into either a video session or an audio-only session.
