Microsoft 365 services experience widespread outage in North America

Widespread Microsoft 365 Outage Reported

Microsoft 365 services, including Teams, SharePoint, and OneDrive, are experiencing a major outage that began at 10:44 AM ET on July 23. The disruption primarily affects users in North America, with Downdetector recording a sharp increase in reports. SharePoint accounts for the majority of complaints, followed by Excel and the Microsoft 365 Admin Center.

Impacted Services and Functionality

The outage has led to degraded functionality across several Microsoft 365 applications. Users are encountering intermittent access to OneDrive, "Something went wrong" errors in SharePoint Online, and degraded chat functionality in Microsoft Teams, including images not loading. The Microsoft 365 Admin Center is loading slowly or not at all, and Power Automate flows are failing to load. Copilot Chat and Microsoft Loop are also experiencing intermittent delays or failures.

Microsoft's Response and Mitigation Efforts

Microsoft has confirmed the degraded status of multiple services and is investigating the issues under incident MO1437424. The company has attempted to reroute traffic for some affected infrastructure, which has resulted in partial recovery for some users. However, services remain impacted for many, and initial attempts to fully resolve the issue were unsuccessful. Microsoft is currently testing new mitigations and expects to share results soon.

Advisory for Business Continuity

Due to the ongoing nature of the outage and the lack of an estimated time for resolution, Microsoft has advised customers to review their business continuity and disaster recovery plans. This recommendation underscores the significant impact of the service disruption on business operations reliant on Microsoft 365.
