Updated July 2, 2026: We have updated the timeline. Thank you for your patience.

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.
