explanation for non-techies**

Microsoft is enhancing its Microsoft 365 Copilot by integrating historical chats into Microsoft Search. Imagine you have a digital assistant that helps you with various tasks and conversations. Now, you can easily revisit any past conversation with this assistant, just like flipping back through a notebook to find a previous discussion. This feature will allow users to search for and retrieve past interactions with Copilot, including chats from notebooks, agents, and the main chat interface.

Think of it like having a personal librarian who can instantly find any conversation you've had with your assistant. This is made possible by a new "Copilot Chats" data source that appears in the search results, allowing users to specifically search for content generated by Copilot. It's similar to having a special section in a library dedicated to your personal notes and interactions.

This feature requires a Microsoft 365 Copilot license and will be available worldwide from November to December 2025. Users will only have access to their own Copilot conversations, ensuring privacy and security. No changes to organization-wide settings or permissions are needed, so administrators don't need to take any action. However, informing users about this new capability can help them make the most of it.

In terms of compliance, this update does involve AI-generated content, which may include user data. It provides a new way for users to interact with AI by allowing them to search and revisit past conversations, enhancing their ability to reuse valuable content. This is like having a powerful search engine that not only finds information but also helps you remember and reuse past insights.
