Successfully configuring guest access in Microsoft Teams requires the coordination of settings across the Microsoft Teams admin center, Azure AD, the Microsoft 365 admin center, and the SharePoint admin center. To configure the guest access portion in Microsoft Teams, follow these steps:
- Navigate to the Microsoft Teams admin center (https://admin.teams.microsoft.com).
- Select Org-wide settings | Guest access:
- Move the slider for Allow guest access in Teams to On to enable guest access in Microsoft Teams.
The ability to enable guest access in Microsoft Teams is dependent on other settings in Azure Active Directory for guest access and Office 365 Groups, as well as settings in the Microsoft 365, SharePoint Online, and OneDrive for Business admin centers.
Once the slider for guest access has been switched to On, the configuration options for guests can be configured, as shown here:
The options available for configuration are listed in the following table:
| Section | Option | Description |
| Calling | Make private calls | If enabled, guests will be able to make peer-to-peer calls. |
| Meeting | Allow IP video | If enabled, guests will be able to use video in calls and meetings. |
| Screen sharing mode | If Allow IP video is enabled, this option manages the screen sharing options: Disabled, Single application, or Entire Screen. | |
