View guest users in a team
Anyone in a team can see all members of a team, including guests, via Manage team in Microsoft Teams. See who's on a team or in a channel has more details.
As an admin, you can use the Office 365 Admin center to view guest users in the tenant. However, this view shows all guest users in the tenant, not just guest users in Microsoft Teams.
- Sign in with your Office 365 global admin account at https://portal.office.com/adminportal/home.
- Go to Users > Guest users.
