How do you turn Guest Access on or off in Microsoft Teams?

Guest access is disabled by default. As a Microsoft 365 or Office 365 administrator, you must enable guest access for Teams before the administrator or team owners can add guests. To enable guest access, work with guests in a team.

After you turn on guest access, it may take several hours for the changes to take effect. If a user sees the “Contact your admin” message when they try to add a guest to their team, guest access is unlikely to be enabled or settings are not in effect yet.

– Important

Enabling guest access depends on the settings in Azure Active Directory, Microsoft 365, or Office 365, SharePoint Online, and Teams. For more information, see Authorizing guest access in Teams.

  • Allow guests to be added to all teams and Microsoft 365 groups
  • Allow or block guest users from a specific team or Microsoft 365 group
