Using groups to enable Frontier access in the Frontier Admin Control

Starting June 2026, Frontier Admin Control will support assigning access via Entra ID groups, enabling scalable pilot management with up to 10,000 enrolled users per tenant (except for All Users enrollment). Admins should prepare by creating groups and monitoring membership; no immediate action is required. Introduction We’re improving the Frontier Admin Control by adding support for Entra ID groups when managing Frontier enrollment. This update helps administrators scale Frontier pilots more efficiently by aligning enrollment with existing access management practices and reducing the need to manage individual users. When this will happen: General Availability (Worldwide): Rollout will begin in early June 2026 and is expected to complete by mid-June 2026. How this affects your organization: Who is affected: Microsoft 365 administrators who manage Frontier access using the Frontier Admin Control. What will happen: What you can do to prepare: No immediate action is required. If you plan to use group-based enrollment: Create or identify a dedicated Entra ID group for Frontier participants. Add the group to the Frontier Admin Control instead of managing individual users. Review group membership regularly to ensure the total enrolled users remain within the 10,000-user limit (if not using All Users). Update internal admin documentation or pilot guidance, if applicable. Compliance considerations: This change introduces an admin control that can be managed through Entra ID group membership. No other compliance impacts were identified. Admins will continue to manage Frontier access from the Frontier Admin Control in the Microsoft 365 admin center. Admins can assign Frontier access using Entra ID groups in addition to individual users.

A maximum of 10,000 enrolled users applies when using specific users and/or groups. Admins will see a warning if adding a group causes the total enrolled user count to exceed this limit. Admins must remove users or groups until the total enrollment is within the limit. Tenants enrolling All Users are not subject to the 10,000-user limit. There […]
