[What and Why]
Copilot Notebooks will be available in Microsoft 365 Copilot Chat for users with Copilot Chat (Basic) and M365 Copilot (Basic) experiences. This update expands Copilot Notebooks beyond users with a Microsoft 365 Copilot add-on license to include additional Copilot Chat users. Copilot Notebooks provides a persistent, AI-powered workspace where users can organize content, add references, and interact with Copilot to reason over their materials in one place.
[Rollout Schedule]
- General Availability (Worldwide): Rollout will begin in mid-June 2026.
