Microsoft Confirms Outlook Outage Affecting Users Worldwide

Microsoft said elevated load across multiple regions is disrupting Outlook and other 365 tools, with Downdetector logging more than 130,000 user reports.

  • On Friday, November 13, Microsoft 365 services remained disrupted as recovery efforts failed to deliver expected results, prompting engineers to explore alternative measures.
  • The disruption began Thursday, primarily affecting Exchange Online and services reliant on its data, such as Outlook and Teams, due to traffic management imbalances overwhelming servers.
  • Downdetector recorded more than 130,000 reports of Outlook problems in the United States at peak disruption. In Australia, users termed it a "Microsoft long weekend."
  • Engineers are restarting servers and changing configurations, though machines remain stuck in a bad state, preventing changes from syncing as expected.
  • Charles Lamanna, Microsoft executive vice-president for Copilot, stated there is no indication the outage resulted from malicious activity, as the company identifies alternative workstreams to increase capacity.
