Microsoft 365 Copilot will now answer questions using your Power BI reports
Starting early June 2026, Microsoft 365 Copilot gains access to Power BI semantic models and reports in Frontier tenants. Users can ask natural language questions and receive answers drawn from existing Power BI content. The feature respects the permissions already set on the reports and semantic models. It is enabled by default and can be turned off by admins in the Microsoft 365 admin center under Copilot settings. Data from the queries is processed through Fabric. A Microsoft 365 Copilot license is required, along with the usual Power BI access rights. No separate Fabric Copilot license is needed.
Before this change, Copilot could only work with text documents, emails, and meeting notes. Power BI numbers stayed inside the reports, and any explanation still had to come from the person who built the model. Now the same Copilot session can reach into semantic models the reader may have inherited or only partially documented. A manager can ask a question in Teams or Outlook and receive totals or trends that the original report builder never intended to expose in that form.
Analysis
Assume every semantic model you publish will soon be readable by Copilot. Spend the next two weeks documenting the top ten measures in each workspace that Copilot will see, including what the numbers actually represent and any known quirks in the calculation.
