Managing a Team
Teams are made up of channels, which are the conversations you have with your teammates. Each channel is dedicated to a specific topic, department, or project.
By default, all members of a team can create channels. A standard channel is open for all members and anything posted is searchable by others. If you need a smaller audience for a specific project, you can create a private channel for your team.
As a team owner, you can add new members and guests, change members into owners, manage channels and settings, and archive a team that's no longer in use.
See the Add members help article and video for more information.
Show and hide channels in Microsoft Teams to keep up with important channels and hide the ones you don't need.
If everyone in your channel needs quick access to a file, turn it into a tab so it's easy to get to. You can turn a specific file into a tab - as long as you or a teammate have already uploaded or shared the file in a message in the chat or channel where you want to create the tab.
