Hello Sastry

I can see that Copilot works in Word and your other Microsoft 365 apps, but the Copilot button in OneNote for Mac is greyed out.

Could you confirm whether you are using a Microsoft 365 Personal/Family subscription or a work/business subscription?

Copilot availability can differ between apps and platforms. Currently, Copilot in OneNote for Mac requires an eligible Microsoft 365 Copilot work/business subscription. With an eligible Personal or Family subscription, Copilot in OneNote is currently supported on Windows rather than macOS, which may explain why the button is unavailable even though Copilot works in Word.

Feel free reply back to this post and update me on this issue, I'll be happy to help.

Hi,

I am using Microsoft 365 Family subscription on MacOS 26.6.1. Also of the shared accounts I am using the main one so have access to Copilot in other apps like Word/Powerpoint etc.

As mentioned I can see the copilot button in the ribbon but it is greyed out:

Hi Sastry

Thank you for confirming the subscription and sharing the screenshot.

The greyed-out button is expected because Copilot in OneNote for Mac currently requires a Microsoft 365 Copilot work subscription. With an eligible Microsoft 365 Personal or Family subscription, Copilot in OneNote is currently supported on Windows only.

You can review the platform requirements here: Welcome to Copilot in OneNote.

This explains why Copilot works in Word and PowerPoint on the Mac but remains unavailable in OneNote.

As a workaround, Copilot in OneNote can be used on a Windows device with the subscription owner’s account.
