Microsoft is working to restore its cloud services following a major outage that disrupted Microsoft 365 applications across 74 countries, leaving businesses and individual users struggling to access essential email, communication and productivity tools.
The disruption affected several Microsoft services, including Outlook, Teams, Copilot, SharePoint and OneDrive. Reports of service problems surged worldwide, with Down detector recording nearly 130,000 reports as users experienced difficulties accessing their accounts and applications.

The outage also affected enterprise operations that rely on Microsoft’s cloud-based services, raising concerns about the impact of disruptions to widely used digital infrastructure.
Microsoft said it was investigating the incident, with early findings pointing to possible server configuration problems. The company also confirmed that there was no indication of a cyberattack.
According to Microsoft, some servers became unexpectedly unavailable following failures during automated checks. The situation was further complicated when restored servers experienced renewed problems as normal levels of user traffic returned.
Engineers deployed several recovery measures, including rolling back updates, restricting traffic to affected servers and redirecting users through alternative infrastructure routes. Exchange Online, which supports Outlook email services, experienced some of the most significant disruption, while Teams chats and meetings were less severely affected.
The company also reported elevated infrastructure loads, which it said were likely contributing to connectivity problems across its services.
In subsequent updates, Microsoft said recovery was progressing across affected regions, with improvements reported in North America and Europe. The company also observed encouraging recovery signals in Asia-Pacific, although some users continued to experience intermittent access problems and delayed email delivery.
In its latest service update, Microsoft said it was seeing sustained improvements in availability as engineers continued restoring the remaining affected infrastructure.
The company cautioned that users might still experience temporary disruptions as applications reconnect and service capacity is restored.
The incident also affected integrations connecting external artificial intelligence platforms to Microsoft’s services. OpenAI reported problems with its Microsoft connectors, including difficulties establishing new connections and disruptions to some connected tools. Anthropic integrations were also reported to have experienced issues.
Although Microsoft has made progress in restoring services, the disruption highlights how heavily businesses depend on cloud platforms for everyday operations, from email and internal communication to file storage and AI-powered productivity tools.
It also reinforces the importance of resilient cloud infrastructure, effective recovery systems and contingency plans as organisations increasingly move essential business activities to digital platforms.
