Manage Copilot access for B2B members within multitenant organizations (MTO) in Teams

  • Applies to: Microsoft Teams

Important

The support discussed in this article is only available to B2B members within the multitenant organization. It isn't available to external or federated users.

Copilot in Teams enhances users’ day-to-day work with features like AI-generated summaries in chats and suggested action items after a meeting. Microsoft now supports B2B member access to Copilot in Teams for licensed users in multitenant organizations to ensure they never lose access to Copilot’s benefits in Team channels and meetings.

B2B member access lets people in your org collaborate with members of other organizations in an external Microsoft Entra organization. This access is done by using Microsoft Entra External ID for business-to-business (B2B) collaboration and granting member-level access to Teams channels, meetings, and other resources in your org. For more information about B2B collaboration, see B2B collaboration.

Note

B2B member access is possible only when both organizations allow access to and from each other. Therefore, you need to coordinate with the external organization’s admin to make sure their cross-tenant access settings allow sharing with you. For more information about cross-tenant access settings, see Overview: Cross-tenant access with Microsoft Entra External ID.

Teams admins can toggle off and on the Allow Copilot for B2B members setting in the Teams admin center or with PowerShell. This setting is turned on by default, allowing external members from other organizations who have Copilot licenses to use Copilot when they join meetings hosted by your organization.

Manage B2B member access to Copilot in the Teams admin center

  1. Sign in to the Teams admin center using your admin credentials.
  2. Expand Users from the left-side navigation pane.
  3. Under Users, select B2B member access.
  4. Either select an existing policy or create a new one.
  5. Toggle the Allow Copilot for B2B members setting On or Off.
  6. Select the Save button.

Manage B2B member access to Copilot using PowerShell

The Allow Copilot for B2B members setting can also be managed using PowerShell with the Get-CsTeamsMultiTenantOrganizationConfiguration and Set-CsTeamsMultiTenantOrganizationConfiguration cmdlets.

To learn how to manage Teams settings using PowerShell, see Manage Teams with Microsoft Teams PowerShell.
