This option includes 28 days of activity data and supports more granular, short‑term insights into Copilot adoption. Exported data will usually reflect copilot activity up to 3 days before the export date; actual timing may vary A minimum of 50 Microsoft 365 Copilot licenses is required. This feature applies to the Viva Insights web app.This message is associated with the Microsoft 365 Roadmap ID 547749.Screenshot 1 - Export data button in Copilot dashboard:Scr
