Microsoft resolves Microsoft 365 outage after cloud disruption

Microsoft has resolved a major outage affecting its Microsoft 365 cloud services, including Outlook and Teams, confirming all systems are operational again as of Saturday morning. The disruption had impacted meeting scheduling, calendar functions, and AI assistant Copilot. The company stated the issue stemmed from an internal network capacity upgrade, not a cyberattack or AI activity, and was unrelated to US flight cancellations. Third-party interfaces with AI services like OpenAI and Anthropic were also temporarily affected during the incident. Experts and industry groups warn the outage highlights risks of Germany's heavy reliance on Microsoft, with 96 percent of companies using foreign digital technologies. They urge greater digital sovereignty and redundant infrastructure to prevent production losses and ensure resilience against future disruptions.
