Hello, Josette Belvedere
Welcome to the Microsoft Community!
When using the Windows operating system, you need to log in with a Windows user account. Windows user accounts come in two types: local accounts and Microsoft accounts. Additionally, Windows user accounts can have either standard user or administrator permissions.
Based on your description, you have two devices, one logged in with a local administrator account and the other with a Microsoft standard user account. When you sync files on device A, the synced files appear on device B but are empty at the document level.
Firstly, the type of user you are using does not affect OneDrive syncing.
You can try the following troubleshooting steps:
1. Confirm if document backup is enabled on your device A.
2. Log in to the OneDrive web version to check if the files backed up on device A were successful.
3. Reconnect OneDrive: This will allow the OneDrive application to re-recognize your subscription status under your Microsoft account, and you need to pause syncing before doing this. Here is a link you can refer to: Unlink and re-link OneDrive - Microsoft Support
4. Reset OneDrive: If OneDrive still cannot sync after reconnecting your account, you can try resetting OneDrive. This will not affect your data, but you should also pause syncing. You can refer to the following link for this: Reset OneDrive - Microsoft Support
5. Check if device B has selected the files synced from device A.
Feel free to contact us if you encounter any problems or new developments while trying the steps!
Thank you for your understanding and patience.
With best regards
