Several major Microsoft services are experiencing widespread outages, including Outlook, Microsoft Teams, Copilot, OneDrive, and Azure.
According to DownDetector, reports of problems have surged, with tens of thousands of users reporting issues for individual Microsoft services. The actual impact could be significantly larger, potentially affecting users and businesses across multiple regions.
However, the outage does not appear to be affecting everyone equally. Some users can still access Microsoft services, while others are experiencing interruptions. Initial testing has also produced mixed results.
We’re investigating reports of users experiencing issues accessing Exchange Online mailboxes through multiple connection methods in the Americas. More details can be found in the Microsoft 365 admin center under EX1550543.

Other Major Online Services Are Reporting Issues
Microsoft isn’t the only company facing problems. Users are also reporting difficulties accessing other popular platforms, including Google, Steam, and Amazon Web Services (AWS). Cloudflare is also seeing reports of service disruptions.
The number of services experiencing problems at roughly the same time raises questions about a possible shared infrastructure issue. However, there is not yet enough confirmed information to establish a common cause.
What Caused the Microsoft Outage?
At the time of writing, the underlying cause of the disruption remains unclear. Microsoft has not yet provided a confirmed explanation in the information available for this report.
It is also too early to determine how long the outage will last or whether the problems affecting multiple companies are connected.
Users should monitor official service-status updates and outage reports for further information as the situation develops.
