When you create a team from an existing Microsoft 365 group, you'll automatically share the same group privacy (public or private) and members as the original group.
Note: Your organization can restrict who can create teams. If you can't create a team or need to turn off team creation, check with your IT admin.
First click Teams on the left side of the app, then click Join or create a team at the bottom of your teams list.
Then click Create team (first card, top left corner).
From here, select Create from…, and choose Microsoft 365 group.
You’ll be presented with a list of groups that you currently own, don't already have a team associated, and have less than 5000 members.
Select your desired group, and a team with the same name will be created automatically. The team will share the same group privacy (public or private) and members as the original group.
This option is not available for groups that have more than 5000 members or have already been used to create another team.
Groups created through Yammer can't be converted to a team.
What to do next
As the creator of the team, you are the owner. Invite people to your team and manage team settings and permissions. For a deeper look at roles and permissions, see Team owner, member, or guest capabilities in Teams.
