You can't directly change privacy settings for individual Teams channels. Channel privacy is determined by the team's overall privacy settings.
Here's how to change your team's privacy settings:
- Go to the team you want to adjust.
- Click on the team name (usually at the top of the screen).
- Select "Manage team" from the dropdown menu.
- Click on "Settings" in the left-hand menu.
- Under "Team privacy," choose the desired privacy level:
- "Public": Anyone in your organization can find and join the team.
- "Private": Only members invited to the team can join.
- Click "Save" to apply your changes.
Note: If you're not a team owner or administrator, you won't be able to change the team's privacy settings.
