Microsoft Outlook outage continues as millions face email disruptions worldwide
Microsoft Outlook is currently experiencing a major global outage. The disruption, which began on Thursday, November 12, 2026, has paralyzed Outlook, Microsoft Teams, and remains ongoing.
Over 430 million people across the globe rely on Microsoft 365. DownDetector noted approximately 140,000 user reports across 74 countries shortly after the disruption.
Status and Cause of Microsoft Outlook being Down
Microsoft has reported a “partial recovery” and improved server stability in some regions. However, the services have not been restored completely across all regions. Users report trouble loading inboxes and receiving and sending emails. Moreover, third-party integrations, including OpenAI and Anthropic connections for Microsoft 365, are also facing disruption. Microsoft has not yet officially confirmed an estimated time for full restoration.
Initial reports suggest that the cause of the outage is server overload. Microsoft noted that processes responsible for establishing secure connections became overwhelmed, leading them to stop processing requests. Microsoft further confirmed that this outage was not caused by a cyberattack or a sudden spike in user traffic.
Early recovery attempts were unsuccessful as restarted servers repeatedly crashed as soon as live user traffic returned. Reports indicate that Microsoft is currently restarting infrastructure in an isolated manner and rerouting traffic across its global network.
Global Institutional Impact
The outage impacted critical government agencies, healthcare networks, airlines, and businesses. Widespread email and scheduling failures caused organizations to rely on backup phone lines and paper workflows. For instance, both the Australian Security Intelligence Organisation (ASIO) and the Australian Federal Police noted that their operations were impacted. Similarly, Los Angeles County departments lost access to internal communication platforms, while New York City Emergency Management notified citizens of delays across online city services.
Canadian hospitals declared a ‘Code Grey,’ indicating infrastructure failure, and directed patients to book appointments via phone instead of email. The scope of the disruption also extended to supply chains and corporate filings. Production timelines faced delays as manufacturing firms in Hong Kong struggled to receive timely order updates from their clients in the US.
Users are advised to rely on secondary messaging apps until the service stabilizes.
