Solution 1Recommended

Verify and Assign the Microsoft Copilot Subscription

Use this solution to ensure that the necessary standalone Copilot license is correctly purchased and assigned to your user profile by an IT administrator.

A common misconception is that Microsoft 365 Business automatically includes Copilot. In reality, Copilot for Microsoft 365 is a premium add-on that requires an additional subscription and explicit assignment to individual users.

1
Check Your Current Account

Open OneNote, go to 'File' > 'Account', and verify that you are signed in with the correct corporate work account.

2
Contact Your Administrator

Reach out to your IT department or Microsoft 365 Global Administrator to confirm your organization has actively purchased the Copilot for Microsoft 365 add-on subscription.

3
Assign the License (For Admins)

Ask the administrator to log into the Microsoft 365 Admin Center, navigate to 'Users' > 'Active users', select your account, and assign the Copilot license under the 'Licenses and apps' tab.

4
Restart OneNote

Once the license is successfully assigned, completely close OneNote and reopen it to allow the system to refresh your license status. The Copilot button should now be active.

License Propagation Time: After a license is assigned in the Admin Center, it may take a few hours for the changes to fully sync and propagate across all Microsoft 365 applications.
