Overview
You can use MS Teams to Chat with one person or more than one person in small groups. These are great for sub-working groups and class project groups.
Note: Group calls via Chat are private and will not show up in Channel history. These are not part of a Team. So if you have a file that is saved in a Microsoft Group, that you want to have this small number of people work on, you'll need to either set up a private Channel in your Team or just link to the file in the Chat.
Instructions
- Log in to Office 365 or open the Teams app on your computer or phone.

- Note: If the group has not yet been created, create a Chat with the person or people you want to talk with by selecting the Start new chat button at the top of the screen and adding in the group member(s).

- Rename the group to a specific topic by selecting the pencil icon next to the team members' names. This will help you stay organized with all your Chats.
