Redmond, Washington: Microsoft said on Saturday (November 14, 2026) that services were fully restored after a massive outage that lasted for hours.
The Resolution
“We have completed our efforts to address the underlying issue of the incident and restored service to the remaining impacted customers and regions,” the company said in an update on X.
Microsoft had earlier said it was “monitoring the backlog of email messages accrued during this event” before considering the issue with enterprise services resolved.
The Scale of the Disruption
Users reported that Microsoft 365 services — including Outlook, Teams and AI assistant Copilot — were interrupted.
Downdetector, an online tracker, said it received outage reports from users in more than 70 countries and territories.
The outage affected governments, courts, healthcare services, businesses, airlines and banks in many places. Governments including those of Japan, Singapore and Australia reported that the hours-long episode had impacted some of their operations.
Over 430 million people use Microsoft 365 apps, according to the company’s website. Problems started appearing around midday Thursday in the U.S.
The Cause
The company apologised on Friday for the disruptions and said the outage was “not related to cyber” or artificial intelligence agents.
It said the incident “was introduced by an issue during an earlier network capacity upgrade that surfaced” following a recent network change.
