How to Remove Copilot From Microsoft 365 Apps Without Removing the License

Many organizations and individual users want to hide or disable the Copilot interface in Microsoft 365 apps like Word, Excel, and Outlook, but they need to keep their Microsoft 365 Copilot license active for other purposes such as API access or future enablement. The Copilot pane appears automatically after a license is assigned, and removing it through standard uninstall options often triggers license deactivation. This article explains how to suppress Copilot in the user interface using Group Policy, registry edits, and Microsoft 365 admin center settings, without touching the license assignment.

Why Copilot Appears in Office Apps After Licensing

When a Microsoft 365 Copilot license is assigned to a user, the Office apps automatically download and activate the Copilot add-in during the next application restart. This add-in creates the Copilot pane on the right side of Word, Excel, PowerPoint, and Outlook. The pane cannot be removed by simply closing it because the add-in reloads each time the app starts. The license itself is stored in Azure Active Directory and is separate from the local add-in files. Therefore, you can block the add-in from loading while keeping the license record intact.

What Happens If You Uninstall the Copilot Add-In Manually

Manually removing the Copilot add-in through the Office Add-ins dialog in Word or Excel does not remove the license. However, the next Office update or repair cycle will reinstall the add-in, causing Copilot to reappear. A permanent suppression method must target the loading mechanism rather than the add-in files themselves.

Method 1: Disable Copilot Using the Microsoft 365 Admin Center

This method hides Copilot for all users in the tenant without modifying local settings. It requires Global Admin or Copilot Admin privileges.

1. Sign in to the Microsoft 365 admin center
   Go to admin.microsoft.com and log in with an account that has Global Administrator or Copilot Administrator role.
2. Navigate to Copilot settings
   Select Settings in the left navigation, then click Copilot.
3. Open the Data sources tab
   In the Copilot settings page, click Data sources.
4. Turn off Copilot for all users
   Set the toggle for Allow Copilot to access your Microsoft Graph data to Off. This prevents Copilot from generating responses and effectively disables the pane in all Office apps.
5. Save changes
   Click Save at the bottom. The change applies within 15 minutes for most users.

Users will still see the Copilot icon, but clicking it will show a message that Copilot is not available. The license remains active in Azure AD.

Method 2: Block Copilot via Group Policy on Windows

For organizations that manage devices with Group Policy, this method prevents the Copilot add-in from loading entirely.

1. Download the latest Office Administrative Templates
   Go to the Microsoft Download Center and download the Office Administrative Template files (ADMX/ADML) for Office 2016 and later. Install the files on your Group Policy management workstation.
2. Open Group Policy Management Console
   Run gpmc.msc and edit the GPO that applies to your target users or computers.
3. Navigate to the Copilot policy setting
   Go to Computer Configuration > Policies > Administrative Templates > Microsoft Office 2016 > Copilot.
4. Enable the BlockCopilot policy
   Double-click Block Copilot, select Enabled, and click OK.
5. Force a Group Policy update on client machines
   Run gpupdate /force on each client or wait for the automatic refresh cycle. Restart all Office apps.

After the policy applies, the Copilot pane no longer appears in any Office app. The license remains assigned and visible in Azure AD.

Method 3: Block Copilot via Registry Edit

If you do not use Group Policy, you can add a registry key on each machine to achieve the same result.

1. Open Registry Editor
   Press Windows + R, type regedit, and press Enter. Click Yes if prompted by User Account Control.
2. Navigate to the Copilot policy key
   Go to HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\office\16.0\common\copilot. If the copilot key does not exist, right-click common, select New > Key, and name it copilot.
3. Create the BlockCopilot DWORD
   Right-click the copilot key, select New > DWORD (32-bit) Value, and name it BlockCopilot.
4. Set the value to 1
   Double-click BlockCopilot, set the Value data to 1, and click OK.
5. Restart Office apps
   Close all Office applications and reopen them. Copilot should no longer appear.

To reverse the change, delete the BlockCopilot DWORD or set its value to 0.

Copilot Still Appears After Applying the Fix

Copilot pane shows a loading spinner indefinitely

This occurs when the admin center setting is off but the add-in is still trying to connect. Close Outlook or Word, restart the app, and wait up to 30 minutes for the admin change to propagate. If the spinner persists, clear the Office cache by deleting the contents of %localappdata%\Microsoft\Office\16.0\Cache.

Group Policy setting is not taking effect

The policy may be applied to the wrong OU or the ADMX files may be outdated. Verify that the GPO is linked to the correct OU containing the users or computers. Run gpresult /h report.html on a client machine and check if the policy appears under Applied Group Policy Objects. If missing, update the Central Store with the latest ADMX files.

Registry edit works only for the current user

The registry path in Method 3 targets HKEY_LOCAL_MACHINE, which applies to all users on the machine. If you accidentally edited HKEY_CURRENT_USER, the change applies only to the logged-in user. Double-check the path and move the key to the correct hive if needed.

Admin Center vs Group Policy vs Registry: Key Differences

Item	Microsoft 365 Admin Center	Group Policy	Registry Edit
Scope	Entire tenant	Specific OUs or computers	Single machine
Reversibility	Toggle setting	Disable policy	Delete or change DWORD
License status	Remains active	Remains active	Remains active
Effect on Copilot icon	Icon visible but nonfunctional	Icon hidden	Icon hidden
Requires admin rights	Global or Copilot Admin	Domain Admin	Local Administrator

You can now remove the Copilot interface from Word, Excel, PowerPoint, and Outlook without losing your Microsoft 365 Copilot license. Start with the admin center method if you need a tenant-wide change without local configuration. For granular control over specific machines, use Group Policy or the registry edit. After applying any method, verify the change by opening an Office app and checking that the Copilot pane no longer loads. If you later decide to restore Copilot, reverse the setting or delete the registry key.
