Microsoft outage continues as planned fixes are not working as expected, company says

Microsoft said the disruption stemmed from server strain as more than 130,000 users reported Outlook problems and other services remained unstable.

  • A major Microsoft 365 outage disrupted Outlook, Teams, and Copilot starting Thursday, November 12, persisting into Friday and affecting tens of thousands of users across more than 70 countries, impacting businesses, government agencies, and emergency services worldwide.
  • Microsoft executive vice-president Charles Lamanna ruled out cyberattacks, attributing the outage to 'elevated load' after numerous servers became 'unexpectedly unavailable,' straining remaining infrastructure and forcing the company to reroute traffic and restart affected systems.
  • Outage tracker Downdetector recorded more than 130,000 reports of Outlook difficulties at peak, while police forces, GP surgeries, and airlines including IndiGo and Air India reported disruptions to email services and activated alternative communication channels.
  • Early Friday, Microsoft reported 'marginal success' in recovery efforts after working 'aggressively' to address service degradation; the company continues implementing traffic optimization measures but has not provided a definitive timeline for full service restoration.
  • The incident exposes vulnerabilities in centralized digital infrastructure, with experts noting 'knock-on effects' when major providers fail; governments have activated contingency plans while Microsoft continues monitoring progress to restore affected regions to full capacity.
