Disable C0-pilot

If this is a personal Microsoft account signed in to Microsoft 365 apps, Copilot can be turned off in each app separately.

Word / Excel / PowerPoint / OneNote on Windows

1. Open the app.
2. Go to File > Options > Copilot.
3. Clear Enable Copilot.
4. Select OK.
5. Close and restart the app.

Word / Excel / PowerPoint on Mac

1. Open the app.
2. Go to the app menu > Preferences > Authoring and Proofing Tools > Copilot.
3. Clear Enable Copilot.
4. Close and restart the app.

Important details:

• The setting is per app, per device. Disabling it in Word does not disable it in Excel.
• If multiple people use the same device, turning it off on that device turns it off for anyone using that device.
• This applies only when signed in with a Microsoft account. These settings are not available for work or school accounts.

If the Enable Copilot option is missing, use the privacy setting instead:

Windows fallback

1. In any Microsoft 365 app, go to File > Account > Account Privacy > Manage Settings.
2. Under Connected experiences, clear Turn on experiences that analyze your content.
3. Select OK.
4. Close and restart the app.

Mac fallback

1. In any Microsoft 365 app, go to the app menu > Preferences > Personal Settings > Privacy.
2. Go to Connected Experiences > Manage Connected Experiences.
3. Clear Turn on experiences that analyze your content.
4. Select OK.
5. Close and restart the app.

This fallback also turns off other features such as suggested replies in Outlook, text predictions in Word, PowerPoint Designer, and automatic alt text for images.

If only Excel formula suggestions are the problem, those can be turned off separately:

1. In Excel, go to File > Options > Copilot.
2. Clear:
   • Show Copilot suggestions for completing formulas
   • Show Copilot suggestions for formulas based on patterns in your content
3. Select OK.

• Turn off Copilot in Microsoft 365 apps | Microsoft Support
• Turn Copilot formula suggestions on or off in Excel
