OneNote Copilot button remains grayed out on Mac despite reinstall

Copilot works in Word with the same Microsoft account, but OneNote 16.111 on macOS Sequoia shows a disabled button even after reinstalling and testing a OneDrive notebook. Because Microsoft’s current guidance ties Copilot availability to the signed-in license and two privacy controls, the next useful step is refreshing the license rather than reinstalling again. Update all Microsoft 365 apps, then in OneNote choose OneNote > About OneNote > More Info > Refresh License. Close every Microsoft 365 app, not only OneNote, and reopen OneNote. In Word, open Word > Preferences > Privacy and confirm both “Experiences that analyze your content” and “All connected experiences” are enabled. Verify OneNote and Word display the same licensed account. If the button remains disabled, contact Microsoft Support with the OneNote version, macOS version, account type, and subscription details so they can check entitlement provisioning; this forum cannot inspect account-specific licensing.
