Overview of teams and channels

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.

Add a tab

Select the plus sign next to the tabs.

For example, add Planner to create a project board for tracking team tasks.

Favorite a channel

If you have a lot of channels, mark important channels as a favorite to make them easy to find.

To add a favorite channel, select the More channels menu below the channels list, and select the start icon for the channel you want to make a favorite.
To remove a favorite, select the three dots next to the channel name, and select Remove favorite.
