The disruption, which began on Thursday, 12 November 2026, affected users across multiple countries and regions, with reports of customers being unable to access email inboxes, send or receive messages, and connect to Microsoft’s online services.
According to reports, the outage extended beyond Outlook to include Microsoft Teams, Copilot, SharePoint, OneDrive and other Microsoft 365 services.
Downdetector, an online outage-monitoring platform, recorded nearly 130,000 reports of Outlook-related problems in the United States at the peak of the disruption. Reports also emerged from numerous countries across the world.
MICROSOFT INVESTIGATES SERVER AND CONNECTIVITY PROBLEMS
Microsoft attributed the disruption to infrastructure problems involving servers becoming unexpectedly unavailable, resulting in increased pressure on the remaining systems.
The company has been working to redistribute connection traffic across its global infrastructure, restart affected servers and introduce alternative technical measures to restore services.
However, Microsoft’s recovery efforts encountered further challenges, with some affected servers reportedly becoming unresponsive again after traffic was redirected to them.
The company continued investigating alternative solutions as the disruption extended into Friday.
BUSINESSES AND ORGANISATIONS FACE COMMUNICATION CHALLENGES
The outage highlights the growing dependence of businesses and institutions on cloud-based email and communication platforms.
Organisations that rely on Microsoft Outlook and Exchange Online for daily business operations may experience communication delays, interrupted customer support, disrupted meetings and difficulties accessing important business correspondence.
For companies operating in sectors such as finance, education, technology and government, interruptions to digital communication services can have significant operational consequences.
