Microsoft says Microsoft 365 fully restored after global outage
Microsoft said access to all Microsoft 365 products has been fully restored, ending a global outage that disrupted government offices, traders, hospitals, and businesses. Bloomberg described it as one of Microsoft’s longest outages, but the supplied report does not give the cause, exact duration, or number of affected customers. The restoration is Microsoft’s own account; independent verification and a technical postmortem were not included.
How the outage unfolded
The disruption began on 12 November 2026, when users in more than 70 countries reported problems with Microsoft 365 as well as Outlook, Teams and Copilot, making the restoration a multi-day incident rather than a brief spike. Microsoft confirmed completion on its Microsoft 365 status page, saying it had “restored service to the remaining impacted customers and regions” and pointing customers to incident MO1550821 in the Microsoft 365 admin center for further updates.
Continuity gap
Organizations that depend on Exchange Online for Outlook mail, Teams calendars, and Copilot faced a disruption Microsoft’s final record put at roughly 30 hours, from 5:05 AM ET on November 12 to 11:10 AM ET on November 13, across multiple regions. That makes a fallback for mail and calendar, not just individual apps, the practical continuity requirement when a single cloud dependency fails.
