Microsoft is currently experiencing a global service disruption on 365

There is currently no confirmed restoration time; as of November 13, 2026, recovery remains in progress, with sporadic improvements but no sustained full recovery reported.^1^

Track the incident

For the most current, tenant-specific information:

1. Sign in to the Microsoft 365 admin center with an administrator account.
2. Go to Health → Service health.
3. Under Active issues Microsoft is working on, open the Outlook or Exchange Online incident.
4. Review Status, Last updated, and All updates for mitigation progress and any restoration estimate.

Service Support Administrator and Helpdesk Administrator roles can also view service health. If the admin center is unavailable, use Microsoft’s public service-status page linked from its service-health guidance.^2^

Because this is an acknowledged service disruption affecting multiple Microsoft 365 services, reinstalling Outlook, rebuilding profiles, or changing local settings is unlikely to resolve it. Wait until Microsoft marks the incident Service restored; Outlook should then recover without client-side changes. A message backlog may take additional time to process after service availability returns.

Administrators can receive updates automatically by opening the incident, selecting Manage notifications for this issue, and adding up to two email addresses.^2^
