An application or feature powered by Windows Copilot to assist users with tasks and productivity
Try these checks in order:
- Confirm the correct account is being used.
- Copilot can use different account types depending on where it is accessed.
- For Copilot on the web, sign in with the same account that works on the laptop and phone.
- If the tablet is signed in with a different account, use the account switcher and sign in again with the correct personal Microsoft account, Apple ID, or Google Account.
- If using the browser on the Fire tablet, open Copilot in the browser and sign in again.
- Copilot is available in a modern web browser at copilot.com.
- If the sign-in page appears but access fails, make sure the browser allows third-party cookies. License validation in Microsoft 365 web apps requires third-party cookies.
- Check browser cookie settings.
- In Chrome: Settings > Privacy and security > ensure Allow third-party cookies is selected.
- In Edge: Settings and More > Settings > Cookies and site permissions > Manage and delete cookies and site data > ensure Block third-party cookies is Off.
- In Firefox: Settings > Privacy & Security > under Enhanced Tracking Protection, select Custom and ensure Cookies is unchecked.
- In Safari on macOS: under Privacy, ensure cross-site tracking prevention and cookie blocking are not enabled.
- If the issue happens only with Microsoft 365 files, verify the file location.
- Copilot may show validation errors when a file is stored in a third-party storage location.
- Move or copy the file to OneDrive or SharePoint, then try again.
- If the tablet is using the updated Copilot experience and content or sign-in looks inconsistent, restart the app or refresh the page.
- Also verify the same sign-in method is being used as before. If the account was previously linked through Google or Apple, use the same sign-in option again.
- If the problem continues, report it from Copilot.
- In the Copilot app, select the ellipsis (…) in the upper-right corner.
- Select Send feedback > Report a problem.
- Include when the issue started, the device, operating system, and a screenshot.
- If the issue is a Copilot license validation error and the steps above do not fix it:
- Home users should contact Support.
- Business users should check with the Microsoft 365 admin.
