Microsoft fixes Outlook outage after global disruption

Microsoft has fully resolved the global Outlook outage that disrupted email services for millions of users on Thursday and Friday. The company confirmed services are fully operational again and apologized, stating the incident was a technical failure, not a cyberattack. The cause was traced to a problem introduced during a network capacity upgrade, which only surfaced after recent network changes. The outage also affected Microsoft 365 services like Teams and Copilot, and severely delayed email traffic for Deutsche Bahn, impacting their ability to send train schedules. Users reported being unable to open emails or attachments despite seeing them in their inboxes. This marks the second major outage for Microsoft's email services in recent months, following a similar incident in late August that was attributed to a cloud infrastructure problem.
