E-Mail-Dienst: Microsoft Outlook weltweit gestört – Systeme laufen wieder an

Ein Fehler in der Cloud-Infrastruktur hat weltweit den E-Mail-Verkehr der Microsoft-Systeme lahmgelegt. Die Systeme erholen sich – doch nicht alle Nutzer sind schon wieder online.

E-Mail-Dienst: Microsoft Outlook weltweit gestört – Systeme laufen wieder an

A widespread outage affecting Microsoft's email services, specifically Outlook, has been resolved. The US company stated that affected systems are now running and available to many users once again. The massive disruption occurred on Monday evening, impacting email traffic for millions of users worldwide. Both Microsoft 365 business customers and Outlook private users were unable to log in or send and receive messages for hours.

Downdetector reported error messages from thousands of users. The issue was traced back to a problem in Microsoft's Exchange Online cloud infrastructure, caused by a fault in a central authentication and connection component that blocked access to servers. Microsoft's engineers initiated corrective measures and implemented targeted repairs during the night.

The company reported that telemetry data indicated a significant recovery, and traffic began to flow again through regular systems. However, some users still need to wait until all delays in email delivery are fully processed and global synchronization runs smoothly.
