Notebooks in the M365 Copilot App

Microsoft 365 Copilot app will introduce Notebooks in early August 2026, enabling users with a Copilot license to organize chats, content, and references in a persistent workspace synced with OneNote. Existing OneNote Notebooks remain unchanged, and no admin action is required.

[What and Why:]

We’re updating the Notebooks experience in the Microsoft 365 Copilot app to help users keep project work organized across conversations. Notebooks bring chats, generated content, and reference materials together in a lightweight, persistent workspace so users can stay in context and move work forward. This update supports personal and team productivity by making it easier to continue work across Microsoft 365 Copilot and OneNote. The existing Notebooks experience in OneNote remains unchanged.

This message is associated with Microsoft 365 Roadmap ID 566318.
