Status of the issue on several Microsoft service

Microsoft has not published a firm restoration ETA for the current widespread Microsoft 365 and Outlook disruption; monitor the tenant-specific incident in Microsoft 365 admin center → Health → Service health for the latest recovery updates.^1^^2^

Check the authoritative incident update

1. Sign in to the Microsoft 365 admin center with an account assigned an appropriate admin role, such as Service Support admin or Helpdesk admin.
2. Open Health → Service health.
3. Under Active issues Microsoft is working on, select the Outlook or Exchange Online incident.
4. Review:
   • Status — for example, Investigating, Restoring service, or Extended recovery.
   • User Impact and Affected services.
   • All Updates for mitigation and recovery progress.
   • Last updated for the freshness of the announcement.

A stated next update time only indicates when Microsoft expects to publish another status message; it is not a guaranteed restoration time. The incident is resolved only when its status changes to Service restored.^2^

Receive updates automatically

From Health → Service health:

1. Select the active incident.
2. Select Manage notifications for this issue.
3. Add the notification addresses and save.

Alternatively, use Customize → Email to subscribe to incidents and status changes for selected services. Microsoft supports up to two notification addresses per administrator.^2^

If the admin center is unavailable, use the public Microsoft service health status page. Because this is affecting multiple organizations or regions, avoid client repair, profile recreation, or device-level changes unless Service health shows no applicable Microsoft incident.

If affected tenants do not see the problem listed, select Report an issue on the Service health page. Microsoft correlates these submissions across organizations and adds an incident or advisory when the issue is confirmed as service-side.^2^
