Copilot in Microsoft OneNote for Windows Desktop Update [MC1185440]

Message ID: MC1185440

[Introduction]

Starting December 12, 2025, Copilot in Microsoft OneNote for Windows desktop will improve the experience for on-canvas Copilot features. Instead of opening a separate window or inserting content directly on the OneNote canvas, features such as Take Notes with Copilot, Summarize Page, Create a Task List, and Rewrite Page will now open in the Copilot Chat pane. This update enables the latest Copilot Chat capabilities for these features, providing a more consistent and integrated experience.
