In Microsoft Teams, teams are groups of people brought together for work, projects, or common interests.
Teams are made up of channels. Each channel is built around a topic, like “Team Events,” a department name, or just for fun. Channels are where you hold meetings, have conversations, and work on files together.
The tabs at the top of each channel link to your favorite files, apps, and services.
If you have a lot of channels, mark important channels as a favorite to make them easy to find.
