Body (from Message Center)

Updated December 8, 2025: We have updated the timeline. Thank you for your patience.

We’re introducing a new capability that enhances Microsoft Copilot by integrating historical Copilot conversations into Microsoft Search. This update allows users to retrieve past interactions—including chats from notebooks, agents, and the main Copilot chat interface—directly within the search results page (SERP). A new “Copilot Chats” data source will also appear in the right rail, enabling users to scope their search specifically to Copilot-generated content.

A Microsoft 365 Copilot license is required to access this feature.

This message is associated with Microsoft 365 Roadmap ID 506751.
