You may see Error Codes 0x8004de85 or 0x8004de8a if there is a problem with your OneDrive account, including a missing account, or a mismatch if you sign in with a personal Microsoft account and a work or school account.
Sign in to your personal Microsoft account or Office 365 account to ensure there are no authentication issues, then check your OneDrive app accounts:
Select the white or blue OneDrive cloud icon in the notification area, at the far right of the taskbar.
Note: You might need to click the Show hidden icons arrow next to the notification area to see the OneDrive icon. If the icon doesn't appear in the notification area, OneDrive might not be running. Select Start, type OneDrive in the search box, and then select OneDrive in the search results.
Select More > Settings.
Select the Account tab to ensure the correct or expected account is being displayed.
