Turn on or off guest access to Microsoft Teams

Important

The new Microsoft Teams & Skype for Business Admin Center is coming soon! Starting in March 2018, we're gradually migrating settings to it from both the current Skype for Business admin center and the Microsoft Teams experience in the Office 365 admin center. If a setting has been migrated, you'll see a notification and then be directed to the setting's location in the new Microsoft Teams & Skype for Business Admin Center. For more information, see Manage Teams during the transition to the new Microsoft Teams and Skype for Business Admin Center.

As the Office 365 admin, you must enable the guest feature before you or your organization's users (specifically, team owners) can add guests.

The guest settings are set in Azure Active Directory. It takes 2 hours to 24 hours for the changes to be effective across your Office 365 organization. If a user sees the message "Contact your administrator" when they try to add a guest to their team, it's likely that either the guest feature hasn't been enabled or the settings haven’t become effective yet.

Important

To enable the full experience of the guest access feature, it's important to understand the core authorization dependency between Microsoft Teams, Azure Active Directory, and Office 365. For more information, see Authorize guest access in Microsoft Teams.
