Updated September 11, 2026: We have updated the timeline. Thank you for your patience. [What and Why:] Administrators can now choose a severity threshold and receive alerts when a new Edge update includes security fixes that meet or exceed that threshold, including zero-day fixes. This helps organizations quickly identify updates that may require attention, while avoiding unnecessary notifications for routine releases. This message is associated with Microsoft 365 Roadmap ID 558435 [Rollout schedule:] General Availability (Worldwide): We will begin rolling out mid-September 2026 (previously early August) and expect to complete by end of September 2026 (previously mid-August). [Impact on your organization:] No action will be taken on behalf of the administrator. By default, the existing experience that notifies admins of all new Edge updates will remain. Admins can now choose to specify when they would like to receive new update notifications. [Action required / Recommendations:] This rollout will happen automatically by the specified date with no admin action required before the rollout.
