Increasing user exception limit to 10,000 for Standard-Deferred release preferences

The user exception limit for Standard-Deferred release preferences is increasing from 100 to 10,000 users per tenant to support larger pilot groups. This change rolls out worldwide from late October to mid-November 2026, allowing more flexible audience management using Microsoft Entra ID groups. No action is required unless expanding exceptions. What and Why: We heard your feedback that the 100-user exception limit was too small to support meaningful pilot and validation audiences, particularly in larger organizations. We previously introduced Microsoft Entra ID group support to simplify audience management. We are now increasing the exception limit from 100 to 10,000 users per tenant, giving administrators more flexibility to manage release readiness at scale. This update lets you assign a larger audience to a release preference different from your tenant-wide selection – for example, keeping a larger validation group on Standard release while the rest of your organization uses Deferred release. Rollout Schedule: General Availability (Worldwide): We will begin rolling out in late October 2026 and expect to complete by mid-November 2026. Impact on Your Organization: Who is affected: Administrators managing Standard and Deferred release preferences in the Microsoft 365 admin center. What is changing: The maximum exception audience increases to 10,000 users per tenant, counting users assigned individually and members of assigned groups together. This is not a per-group allowance or a limit on your organization total users. You can continue using Microsoft Entra ID security groups to manage exceptions. Nested groups remain unsupported. If your tenant uses Deferred release, you can assign a larger group of IT staff, help desk personnel, and business representatives to Standard release to evaluate eligible updates earlier. If your tenant uses Standard release, you can assign a larger audience to Deferred release when those users need additional preparation time. If a customer adds a group with more than 10,000 users, they will receive a message, during addition, notifying them of the limit. If they add a group that later exceeds the limit, only the first 10,000 users will be included. The Release preferences in MAC will display a message asking them to remove the users […]
