Summary
- Microsoft is updating Microsoft 365 usage reporting calculations for Microsoft Browser and Visio to improve accuracy and workload-specific analytics.
- Browser usage reports will expand to include additional Microsoft 365 apps such as Copilot App, OneNote, and Outlook, which may raise active-user counts.
- Visio usage reporting will change how Desktop and Web usage are classified, which may also increase active-user counts.
- Historical reporting data will not be recalculated, so reporting baselines may shift going forward.
- Administrators should review dashboards and any Microsoft Graph Reports API integrations that rely on these metrics.
Microsoft is updating browser and Visio usage reports in late September 2026 to improve metric accuracy and expand application coverage. Active user counts may increase across tenant reports and Graph API outputs, though historical data will remain unchanged. Administrators should note the baseline change date, update internal dashboards, and validate any automated API integrations to prevent false trend anomalies.
Administrator impact: Administrators must review internal reporting dashboards and validate any Microsoft Graph API integrations affected by the metric changes.
End user impact: No direct end user impact is expected.
Score rationale: The update modifies usage reporting metrics and API outputs without disrupting core service functionality.
Microsoft is updating Microsoft Browser and Visio usage reports on September 21, 2026, improving metric accuracy and including more apps. Active-user counts may rise, but historical data won’t change. Administrators should review reports, note the baseline change date, and validate API integrations.
