Microsoft resolves global outage affecting Outlook and Teams after 36 hours

Microsoft has resolved a global outage affecting its services, including Outlook and Teams, after more than 36 hours. The disruption, which began on November 12, impacted users across multiple countries. The outage primarily affected Exchange Online, disrupting access to emails, calendars, virtual meetings, and cloud-based applications. Microsoft confirmed it was a technical issue, not a cyberattack or AI-related, and apologized for the inconvenience caused to businesses, government agencies, and schools. The root cause was traced to a faulty network capacity upgrade, which led to unexpected server failures. Engineering teams restored capacity and rerouted traffic, and services are being gradually normalized while stability is monitored.
