There are different ways to turn off or remove Copilot depending on where it appears (Microsoft 365 apps like Word/Excel/PowerPoint/Outlook, or the Copilot app on Windows). The steps below use only documented options.
- Turn off Copilot in Word, Excel, PowerPoint, OneNote (Microsoft 365 apps)
On Windows or Mac desktop apps (where supported), use the Enable Copilot checkbox:
- Open the app (for example, Word).
- Go to the app’s settings/preferences where the Enable Copilot option is exposed (per the article, it is a separate checkbox per app).
- Clear (uncheck) Enable Copilot.
- This disables Copilot in that specific app on that specific device.
- Repeat in each app (Word, Excel, PowerPoint, OneNote) and on each device where Copilot should be off.
- When Copilot is turned off this way, the Copilot icon on the ribbon is disabled and Copilot capabilities in that app cannot be used.
Important details from the documentation:
- The Enable Copilot checkbox is available (as of March 13, 2025) starting with these versions:
- Windows:
- Word: Version 2412
- Excel: Version 2501
- PowerPoint: Version 2501
- OneNote: Version 2502
- Mac:
- Word: Version 16.93
- Excel: Version 16.93.2
- PowerPoint: Version 16.93.2
- Windows:
- If the checkbox is not visible, check the app version and update to at least the versions listed in the article.
- Copilot cannot be turned off in the iOS, Android, or web versions of Word, Excel, or PowerPoint using this checkbox. For those, only privacy/connected-experience controls apply (see step 3).
- Turn off Copilot in Outlook
Outlook uses a Turn on Copilot toggle instead of the Enable Copilot checkbox.
As of June 3, 2025, the toggle is available in:
- Outlook for Android: Quick Settings > Copilot
- Outlook for iOS: Quick Settings > Copilot
- Outlook for Mac: Quick Settings > Copilot
- Outlook on the web: Settings > Copilot
- Outlook for Windows (new Outlook): Settings > Copilot
Steps:
- Open Outlook on one of the supported platforms above.
- Go to the location listed (Quick Settings or Settings).
- Find the Copilot section and turn off the Turn on Copilot toggle.
Key behavior:
- Turning off Copilot via this toggle in Outlook applies to all devices where the same account is used in Outlook. For example, turning it off on Outlook for Mac will also turn it off for that account on Outlook for iOS.
- There is currently no date for when this on/off control will be available in classic Outlook on Windows.
- Turn off Copilot by changing Microsoft 365 privacy/connected experiences
If the Enable Copilot checkbox is not available yet in a given app, Copilot can be turned off by disabling certain connected experiences via account privacy settings. This is more drastic because it also disables other cloud features.
Behavior noted in the documentation:
- Changing privacy settings to turn off Copilot also turns off other features such as:
- Suggested replies in Outlook
- Text predictions in Word
- PowerPoint Designer
- Automatic alt text for images
- For the full list of affected features, see the “Connected experiences in Office” documentation referenced in the article.
- Remove or uninstall the Microsoft Copilot app on Windows
If Copilot appears as a standalone app on Windows (Copilot app / consumer experience), it can be uninstalled like any other app.
On Windows 11:
- Open Settings > Apps > Installed apps.
- Search for Copilot.
- Select the … (three dots) next to Copilot.
- Select Uninstall.
On Windows 10:
- Open Settings > Apps.
- Search for Copilot.
- Select Uninstall.
Notes from the documentation:
- Copilot is an app and can be uninstalled from these locations.
- For advanced users or IT admins, Copilot can also be removed or blocked via:
- A PowerShell script (see “Remove the Copilot app” in the Windows client management documentation).
- AppLocker policy to prevent installation of the MICROSOFT.COPILOT package (recommended instead of the legacy TurnOffWindowsCopilot policy, which is subject to deprecation).
- The Copilot app can be reinstalled from the Microsoft Store if needed.
- Known issues with intrusive Copilot icons in Word
Some users have reported intrusive Copilot icons or logos in Word even after disabling Copilot. Moderator responses in Microsoft Q&A indicate:
- The 16.103.1 update for Word (Classic 365 / Mac scenarios referenced) removed the intrusive Copilot logo in the lower-right corner of the document window.
- This update was initially available on the Current Channel (Preview) and then rolled out more broadly.
If intrusive Copilot icons remain after disabling Copilot:
- Ensure the app is updated to at least the version where the fix is included (e.g., 16.103.1 in the referenced Mac/Classic 365 cases).
- Confirm Enable Copilot is unchecked in Word.
- Important scope note
- The documented “Turn off Copilot in Microsoft 365 apps” article explicitly applies when signed in with a Microsoft account (for example, a personal outlook.com address).
- Enterprise/organizational environments may use additional admin policies (such as AppLocker or MDM policies) to control Copilot, which are not fully detailed in this context.
