How to Hide Copilot Button in Word Excel PowerPoint and Outlook

If you use Microsoft 365 apps like Word, Excel, PowerPoint, or Outlook, you may see a Copilot button on the ribbon. This button opens the Copilot pane, which provides AI-powered suggestions and automation. Some users prefer to remove this button to reduce visual clutter or because their organization does not use Copilot. This article explains how to hide the Copilot button in each of these applications using built-in ribbon customization options. You do not need administrator permissions to apply these steps for your own account.

Why the Copilot Button Appears in Office Apps

The Copilot button is part of the Microsoft 365 Copilot feature, which integrates generative AI into Word, Excel, PowerPoint, and Outlook. Microsoft added this button to the ribbon by default in recent updates. The button appears on the Home tab in each app. Clicking it opens the Copilot pane, where you can ask questions, generate content, or summarize data. Hiding the button does not disable Copilot functionality. It only removes the visual element from the ribbon. You can still access Copilot through the View tab if needed.

The ribbon customization feature is built into all desktop versions of Microsoft 365. You can hide any ribbon button, including Copilot, without installing third-party tools or editing the registry. The steps are identical across Word, Excel, and PowerPoint. Outlook uses a slightly different ribbon layout, but the method is the same.

Steps to Hide the Copilot Button in Word, Excel, and PowerPoint

Follow these steps to remove the Copilot button from the ribbon in Word, Excel, or PowerPoint. The process is identical for all three applications.

1. Open the application and right-click the ribbon
   Launch Word, Excel, or PowerPoint. Right-click anywhere on the ribbon area at the top of the window. A context menu appears.
2. Select Customize the Ribbon
   From the context menu, click Customize the Ribbon. The Word Options dialog opens with the Customize Ribbon category selected.
3. Locate the Copilot checkbox
   In the right pane labeled Customize the Ribbon, expand the Home tab group by clicking the plus sign next to it. Scroll down until you see the Copilot entry. It appears as a checkbox under the Home tab.
4. Uncheck the Copilot checkbox
   Click the checkbox next to Copilot to remove the checkmark. The Copilot button is now hidden from the ribbon.
5. Click OK to save changes
   Click the OK button at the bottom of the dialog. The ribbon updates immediately. The Copilot button disappears from the Home tab.

To restore the button later, repeat the same steps and recheck the Copilot checkbox.

Steps to Hide the Copilot Button in Outlook

Outlook uses a different ribbon structure because it combines mail, calendar, and other views. The Copilot button appears only in the mail view. Follow these steps to hide it.

1. Open Outlook and switch to Mail view
   Launch Outlook. Click the Mail icon in the bottom-left corner to ensure you are in the mail view.
2. Right-click the ribbon and choose Customize the Ribbon
   Right-click anywhere on the ribbon. Select Customize the Ribbon from the context menu. The Outlook Options dialog opens.
3. Select the Mail tab group
   In the right pane, ensure Main Tabs is selected in the dropdown. Expand the Home (Mail) tab group by clicking the plus sign next to it.
4. Uncheck Copilot under Home (Mail)
   Scroll down until you see the Copilot checkbox under the Home (Mail) tab. Click the checkbox to remove the checkmark.
5. Click OK to apply
   Click OK. The Copilot button is removed from the ribbon in the mail view.

The Copilot button does not appear in calendar, contacts, or tasks views by default. You only need to hide it in the mail view.

Common Issues and Limitations When Hiding Copilot

The Copilot button reappears after a Microsoft 365 update

Microsoft occasionally resets ribbon customizations during feature updates. If the Copilot button returns after an update, repeat the steps above. To prevent this, export your ribbon customizations. In the Customize Ribbon dialog, click the Import/Export button at the bottom-right. Choose Export all customizations and save the file. After an update, import the file using the same button.

Hiding the button does not disable Copilot data processing

Removing the button only hides the visual entry point. Copilot remains active in the background if your organization has enabled it. Data processing and AI suggestions continue. To fully disable Copilot, you must use Group Policy or the Microsoft 365 admin center. This requires administrator privileges.

The checkbox is grayed out or missing

If the Copilot checkbox is grayed out, it means your IT administrator has locked the ribbon customization. You cannot hide the button in this case. Contact your administrator to request a change. If the checkbox is entirely absent, your version of Microsoft 365 may not include Copilot. The button may appear but cannot be customized. In this scenario, you can use the Minimize the Ribbon option (Ctrl+F1) to collapse the entire ribbon temporarily.

Copilot Button Visibility: Desktop vs Web vs Mobile

Item	Desktop App	Web App	Mobile App
Customization method	Right-click ribbon > Customize the Ribbon	No built-in hide option	No built-in hide option
Button location	Home tab	Top-right toolbar area	Floating icon or toolbar
Persistence across updates	Can be reset by updates	N/A	N/A

The web and mobile versions of Word, Excel, PowerPoint, and Outlook do not offer a user-facing option to hide the Copilot button. If you primarily use these platforms, you cannot remove the button without browser extensions or third-party tools. The desktop app provides the only reliable method for hiding the button.

Conclusion

You can now hide the Copilot button in Word, Excel, PowerPoint, and Outlook using the Customize Ribbon dialog. The process takes less than one minute per application. For Outlook, you must perform the steps in the mail view. Remember that hiding the button does not disable Copilot. If your organization requires Copilot to be fully removed, ask your IT administrator to apply a Group Policy setting. For additional ribbon customization, explore the Customize Ribbon dialog to add or remove other buttons as needed.
