Microsoft 365 suffers worldwide outage

A major and ongoing outage affecting multiple Microsoft 365 services worldwide has occurred just before 5:00AM AEDT today.

Potentially impacted services include Exchange Online, Microsoft Teams, SharePoint Online and Microsoft Copilot 365.

Microsoft Defender XDR, Microsoft Planner, Microsoft To Do, Microsoft Intune and Microsoft Defender for Office 365 are also potentially affected.

Multiple Microsoft Purview services including Authorization, Auto Labelling, Data Loss Prevention (DLP), Communication Compliance, and Data Classification are impacted. All Power BI users may also intermittently be unable to export reports with MIP sensitivity labels to PDF in Power BI.

The company stated that it is "continuing to work through restarting and validating the affected servers to safely return them to service" as it explores opportunities to expedite this process.

"In parallel, we're assessing whether reverting the small number of recent configuration updates we identified could help accelerate recovery," the latest update on Microsoft's service health status page said.

Previous updates stated that Microsoft had validated an alternative health check method on a subset of affected infrastructure, which allowed the servers in that subset to successfully return to service, with the change now applying more broadly.

"We're also preparing an automated recovery process to continually detect and restart unresponsive servers, to help keep them in service while this change progresses," the company stated.

"Additionally, our review of recent changes has identified a small number of configuration updates that we're investigating as potential contributors to the issue." 

Microsoft's Azure was affected by a global outage back in October 2025.

The same month, AWS suffered a major outage that disrupted apps and services worldwide.
