Microsoft 365 admin center: Usage reports - Copilot Chat - Usage intensity and new app coverage

The Copilot Chat usage report will include metrics on prompts submitted and expanded coverage across new host applications. Admins will now see total and average prompt counts at both tenant and user levels, along with user activity insights such as active days and last activity dates. Additionally, the report introduces visibility into Copilot Chat usage within Word, Excel, PowerPoint, and OneNote—enabling better tracking of adoption and engagement across these core Microsoft 365 apps. All metrics focus on unlicensed users and support export functionality for further analysis. User-level information is anonymized by default. #copilotcontrolsystem
