💡 Our Technical Review in summary
Summary
Microsoft 365 admin center usage reports experienced significant data delays between March 13, 2026, and March 22, 2026. The issue was caused by an upstream data source pipeline failure, which prevented usage statistics from being processed and displayed in a timely manner. Affected reporting areas included:
- Microsoft Teams: User Activity reports were delayed primarily for North American tenants.
- Microsoft Copilot: Reports were delayed globally and in specific regions like Europe.
- Adoption Score: Reports showed data as old as March 5, 2026, across various regions.
Impact
IT Administrators attempting to monitor service adoption or user activity within the Microsoft 365 admin center encountered stale data. During the peak of the incident, data for some services was delayed by several days, falling outside of standard Service Level Agreement (SLA) thresholds. This impacted decision-making and reporting for Teams, Copilot, and general service adoption.
Status
Service Restored. Microsoft has successfully processed the backlog of usage data and addressed the underlying upstream pipeline issues. Internal telemetry confirms that all reporting data is now accurate and up to date as of March 22, 2026, at 3:20 AM UTC. Microsoft is currently analyzing the pipeline failure to prevent future occurrences.
