Is there a way to reopen OneDrive which was automatically backing up on which the computer crashed?er

To regain access to OneDrive after a crash, you can follow these steps:

1. Check OneDrive Status: Ensure that OneDrive is running on your old computer (Windows 10). If it is not running, you can try to manually start it.
2. Sign In to OneDrive: On the old computer, open OneDrive and sign in with the same Microsoft account that was used on the crashed Windows 11 machine. This should allow you to access your files stored in OneDrive.
3. Recover Files: If you had files that were being backed up to OneDrive, they should still be available in the OneDrive folder on the old computer. You can check the OneDrive folder to see if your Excel files are there.
4. Use Microsoft Support and Recovery Assistant: If you encounter issues logging in or syncing, consider using the Microsoft Support and Recovery Assistant, which can help diagnose and fix problems with OneDrive.
5. Reset OneDrive: If you still face issues, you may want to reset OneDrive on the old computer. This can sometimes resolve sync issues and allow you to access your files again. Instructions for resetting OneDrive can be found in the Microsoft support documentation.

If the problem persists, you may need to check for any specific error messages and consult Microsoft support for further assistance.
