What the notice says

Microsoft's text, with its sections, lists and tables; source markup removed

Updated September 17, 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-October 2026 (previously mid-September) and expect to complete by end of October 2026 (previously end of September).

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.
