Microsoft is rolling out a new role-based access control (RBAC) role designed to simplify external collaboration management in Microsoft Teams.
The Teams External Collaboration Administrator role will become available starting late January 2026, with full global deployment expected by mid-February 2026.
The new administrative role provides organizations with a targeted approach to delegating external collaboration responsibilities.
Rather than granting full Teams administrator privileges to staff members who only need to manage federation settings. Administrators can now assign the more limited Teams External Collaboration Administrator role.
This granular access control aligns with security best practices by implementing the principle of least privilege. Ensuring employees have only the permissions necessary for their specific responsibilities.
Key Capabilities
The Teams External Collaboration Administrator role empowers designated staff to:
| Task | Description |
|---|---|
| Manage external access settings for federated domains | Control which external organizations can communicate with your users via Teams. |
| Configure External Access Policies | Allow or block specific external domains from connecting with your organization. |
| Oversee federation settings without broader Teams admin permissions | Manage federation and external access without needing full Teams admin rights. |
Organizations should note that this role is subject to specific restrictions. Administrators assigned this role cannot access the Teams admin center portal; all management must occur through PowerShell commands.
Additionally, assignment to Administrative Units is not currently supported. Global administrators can assign the new role through either the Microsoft Entra admin center or the Microsoft 365 admin center.
The rollout requires no action from administrators before the February completion date. To prepare for this rollout, organizations should notify Global admins of the new role’s availability.
Update internal documentation and training materials to reflect the role and its capabilities. Review compliance requirements based on organizational policies and regulations.
This announcement represents Microsoft’s continued commitment to providing flexible administrative tools that support secure delegation of responsibilities.
Organizations managing large-scale federated Teams environments will benefit from this more precise permission structure.
For additional guidance, administrators can reference Microsoft’s documentation on Teams administrator roles and Microsoft Entra built-in roles available on Microsoft Learn.
