Turn off Copilot in all Office applications

I do not see the Exable Copilot Under File/Options anywhere. I'm using the DESKTOP VERSION of office apps from m365

Refer to https://support.microsoft.com/en-us/office/turn-off-copilot-in-microsoft-365-apps-bc7e530b-152d-4123-8e78-edc06f8b85f1

If you want to turn off Copilot in a Microsoft 365 app (for example, Word, PowerPoint, and Excel), you can ​​​clear the Enable Copilot checkbox in the app on your Windows or Mac device. When you turn off Copilot in an app, the Copilot icon on the ribbon is disabled and you won't be able to use any Copilot capabilities in that app.

As an alternative to turning off Copilot, you can remove the Copilot icon from the ribbon. For more info, see Customize the ribbon in Office. Removing the icon from the ribbon doesn't turn off Copilot; you can still access Copilot through other methods, such as the shortcut menu.

Use the "Enable Copilot" checkbox to turn off Copilot in Word, PowerPoint, and Excel

Note: For information about Outlook, see the Use the “Turn on Copilot” toggle to turn off Copilot in Outlook section later in this article.

There is a separate Enable Copilot checkbox in each app and the checkbox only applies to that app on that device. For example, if you want to turn off Copilot in Word and Excel, you need to go to both apps and clear the Enable Copilot checkbox. If you have multiple devices, you need to go to each device and clear the Enable Copilot checkbox for each app. Also, turning off Copilot on a device turns off Copilot for anybody using that device.

As of March 13, 2025, the Enable Copilot checkbox is available in the following apps starting with the versions listed:

On Windows: 

Word: Version 2412

  Excel: Version 2501
  
     PowerPoint: Version 2501
     
        OneNote: Version 2502
        
        On Mac:
        
           Word: Version 16.93
           
              Excel: Version 16.93.2
              
                 PowerPoint: Version 16.93.2
                 

If you don't see the Enable Copilot checkbox in the app, check which version of the app that you have. If necessary, update your version of the app on your device.

Note: You can’t turn off Copilot in the iOS, Android, or web versions of Word, Excel, or PowerPoint.

In the meantime, you can change your privacy settings to turn off Copilot.

Clear the "Enable Copilot" checkbox on Windows devices

In your app (for example, Excel), go to File > Options > Copilot.

Clear the Enable Copilot checkbox.

Select OK, and then close and restart the app.

If you want to turn Copilot back on, repeat these steps, but select the Enable Copilot checkbox in Step 2.

Clearing the Enable Copilot checkbox allows you to turn off Copilot without having to change your account privacy settings. If you previously changed your account privacy settings to turn off Copilot, you can change your account privacy settings back to their previous setting. To change your account privacy settings, see Change privacy settings on Windows devices.
