Microsoft Outlook

There is no published universal restoration time for the reported Outlook disruption; your organization’s latest status and any estimated recovery time are shown in its Microsoft 365 Service health incident record.

Check the incident update

1. Sign in to the Microsoft 365 admin center with a Global Reader, Service Support Administrator, Helpdesk Administrator, or other account permitted to view service health.
2. Open Health → Service health.
3. Under Active issues Microsoft is working on, select the Outlook or Exchange Online incident.
4. Review Status, User impact, Last updated, and All updates. Microsoft posts investigation, mitigation, and restoration progress there. ^1^

If no matching incident appears, select Report an issue on the Service health page. This submits the tenant’s symptoms for correlation with reports from other organizations.

Receive updates automatically

Open the incident and select Manage notifications for this issue to receive email updates. For broader alerts, use Customize → Email, enable service-health notifications, and select the relevant services. ^1^

If the admin center itself is unavailable, use the public Microsoft service-status page. It can identify broader known outages, but the admin center contains the detailed, tenant-specific incident information. ^2^

The Classic Outlook known-issues page tracks client defects and workarounds; it is not the authoritative source for live Microsoft 365 service-outage recovery estimates. ^3^
