MS Outlook, MS Form, other MS Apps Is Not Working

Microsoft currently reports a Microsoft 365 service degradation, so monitor the incident in Service health rather than changing Outlook or Forms settings while recovery is underway.^1^

The public notice was last updated November 12, 2026 at 7:30:36 PM UTC. No estimated resolution time is included in the available notice. Outlook’s inability to send or receive mail and Forms failing to open may therefore be related to this broader incident.

Track the incident

If you are a Microsoft 365 administrator:

1. Sign in to the Microsoft 365 admin center.
2. Select Health → Service health.
3. Under Active issues Microsoft is working on, open the relevant incident.
4. Review Status, User impact, Affected services, Last updated, and All updates.

Service health access is available to appropriate administrator roles, including Service Support Administrator and Helpdesk Administrator. Microsoft posts investigation, mitigation, recovery, and final resolution updates on the incident page.^2^

If the admin center is unavailable or you are not an administrator:

• Check the public Microsoft service health status page.^1^
• Ask your organization’s Microsoft 365 administrator for the tenant-specific incident details.
• Microsoft also publishes updates for certain events through @MSFT365status on X.^2^

Receive automatic updates

An administrator can configure notifications from:

1. Microsoft 365 admin center → Health → Service health.
2. Select Customize → Email.
3. Enable Send me email notifications about service health.
4. Choose incidents or advisories and the services to monitor.

For one incident only, open it and select Manage notifications for this issue. Up to two notification addresses can be configured per administrator. The Microsoft 365 Admin mobile app can also provide push notifications.^2^

How resolution is confirmed

The incident is resolved when its status changes to Service restored. Microsoft defines this as confirmation that corrective action resolved the underlying problem and the service returned to a healthy state. The completed event then appears under Issue history, where incidents and advisories remain available for the previous 7 or 30 days.^2^

After that status appears, retest Outlook and Forms. If either remains unavailable while Service health shows no relevant active issue, an administrator should select Report an issue on the Service health page so Microsoft can assess tenant-specific reports.^2^
