Microsoft is still tracking a widespread Microsoft 365 service disruption affecting Outlook, Microsoft 365 Copilot, and sign-in as of November 13, 2026; no confirmed public restoration time is currently available.^1^^2^
Check the latest status
- Because Microsoft 365 sign-in is also failing, monitor the unauthenticated Microsoft public service-health page. Microsoft specifically recommends this page when users cannot access the admin center.^3^
- If this is a work or school account and an administrator can sign in, open Microsoft 365 admin center → Health → Service health → Active issues Microsoft is working on. This provides tenant-specific incident details and is more precise than the public page.^3^
- Look for the incident’s next-update time or a status change to Service restored. A mitigation-in-progress message is not a guaranteed recovery time.
Since Outlook, Copilot, and Microsoft 365 sign-in stopped together, avoid changing passwords, reinstalling applications, or removing accounts while the incident remains active. If the status page reports recovery but access still fails afterward, contact your organization’s Microsoft 365 administrator so they can check whether your tenant remains affected and open a Microsoft support request.
