Outlook outage 11-12-26

Microsoft has not published a restoration ETA for the November 12 Outlook/Exchange Online outage; the next status update was scheduled for 10:30 PM UTC (5:30 PM EST in Ohio), which is an update time—not a promised recovery time.

Microsoft is expanding mitigation across affected infrastructure and preparing automated recovery, but those actions do not establish when service will be fully restored. The public notice also does not provide an Ohio-specific ETA. User reports indicate Outlook problems across the United States, including Ohio ^1^.

Where to monitor the incident

For a business Microsoft 365 account, ask an administrator to check:

1. Microsoft 365 admin center
2. Health → Service health
3. Open the active Exchange Online/Microsoft 365 incident under Active issues Microsoft is working on
4. Review All updates for mitigation progress and any eventual restoration estimate

Service health displays the incident status, affected services, user impact, and Microsoft’s ongoing updates. Service Support administrators and Helpdesk administrators can also view it ^2^.

If the admin center cannot be reached, use Microsoft’s public Service status page linked from that same documentation. Administrators can also enable incident notifications through Service health → Customize → Email.

No Outlook reinstall, profile recreation, or other client-side change should accelerate recovery from an acknowledged service incident. Outlook should recover as Microsoft completes mitigation; if your tenant remains affected after Microsoft marks the incident Service restored, the administrator should use Service health → Report an issue.
