Großstörung: Microsoft stellt Betrieb von Outlook und Teams wieder vollständig her

Düsseldorf – After more than 24 hours, Microsoft has fully restored service to its Outlook and Teams platforms, the tech giant announced on X. The US software company attributed the cause to server issues that also affected its AI assistant, Copilot. No signs of malicious activity were reported. The widespread global outage impacted businesses, governments, and users worldwide.

The problems began on Thursday evening and escalated into one of Microsoft's longest outages. The disruption had significant effects on companies and governments globally, as Outlook and Teams are among the most widely used office applications. Hundreds of millions of users temporarily could not send emails, manage calendars, or host video conferences.

Microsoft stated that functions linked to the cloud-based email and calendar service, Exchange Online, were particularly affected. Other unrelated applications, however, continued to operate normally.
