Scope of impact
Any admin expecting reports from the affected scenarios as outlined in the More info section may have been affected.
Root cause
A recent change to an upstream part of the data processing pipeline resulted in delays impacting report generation.
Next steps:
- We're analyzing the data we've gathered from this issue in order to develop improvements to our proactive remediation procedures to prevent similar impact from reoccurring.
This is the final update for the event.
Final status
After confirming that the upstream data pipeline adjustments had remediated the source of the issue and continuing to monitor report generation, we've validated that fresh usage reports are being created as expected and that all previous usage data is now available to admins.

Our efforts to make upstream data pipeline adjustments and report migrations to address the remaining reporting delays are ongoing, and at this time most affected data pipelines and reports have already been restored. Additionally, we've further confirmed no usage report data was lost as a result of this issue. We are continuing to monitor recovery until data freshness is fully restored across all remaining reports and are implementing preventive measures to help avoid similar issues in the future.

We're continuing to make upstream data pipeline adjustments and report migrations to address the remaining reporting delays. We'll provide a timeline for remediation as soon as one becomes available.

We're progressing with our upstream data pipeline adjustments to address the remaining reporting delays admins are encountering. Copilot Usage and Copilot Chat Usage reports delays have subsided and we're completing our mitigations for Copilot Readiness reports, Copilot Adoption reports, Microsoft 365 App & Active user reports, and Teams App reports. We're expecting an estimated timeline for the remediation of the impact for all reports will be available by our next scheduled communication update.
- Aug 24, 2026, 19:53 CEST
We've begun the process of applying mitigations for the report latency, and have confirmed that Copilot Usage and Copilot Chat Usage reports have recovered thanks to these mitigations. We're recovering the remaining impacted reports, and will provide an updated timeline for full remediation as soon as one becomes available.
- Aug 21, 2026, 19:31 CEST
Our monitoring has identified an increase report generation delays and our investigation has identified that an upstream component that facilitates report data access and generation isn't responding as expected, resulting in impact. We're in the process of identifying the underlying cause of impact and develop a remediation strategy.
