      Enable Guest Access for Teams

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

      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 aren't effective yet.

      Configure guest access in the Microsoft Teams admin center

      1. Sign in to the Microsoft Teams admin center.

      2. Select Org-wide settings > Guest access.

      3. Set the Allow guest access in Microsoft Teams toggle switch to On.

      4. Set the toggles under Calling, Meeting, and Messaging to On or Off, depending on the capabilities you want to allow for guest users.

        • Make private calls – Turn this setting On to allow guests to make peer-to-peer calls.
