OneDrive error code 0x8004de8a
on Windows

I can’t sign in to OneDrive and keep getting an error code 0x8004de8a. It says there’s a problem with my account, but I’m sure the login info is correct. Could you help me, maybe?

Usually, the OneDrive error code 0x8004de8a in Windows is related to an issue with account authentication. Users typically see that error at sign-in time due to a system update, some sort of password change to their Microsoft account, or an interruption in syncing files and folders. The error description may lead you to think you are trying to sign in with the wrong credentials. However, the real issue is likely a more complicated one.

The bug that causes error 0x8004de8a is commonly related to the account credentials stored in Windows that do not match the Microsoft account you are trying to sign in with. This can occur if you have changed the password associated with the account, switched between logon accounts (local and Microsoft), or changed devices you wish to sign into.

It can also occur if there is corruption occurring on OneDrive, such as the app's configuration or cached sign-in data. Some other users mentioned that they see this error after restoring their system back to a prior date or after the modification of group policy settings.

In some isolated instances, missing Windows updates used by OneDrive or having a premature connection between the OneDrive client and the Microsoft account service will cultivate this error as well. In addition, if some of the required services to run synchronizations within OneDrive are not operational (like the Microsoft Account Sign-in Assistant), you will continue to see this error code.

To resolve OneDrive error 0x8004de8a, users often need to re-enter their login credentials, clear the OneDrive credentials from Windows Credential Manager, or reset the OneDrive app altogether. When these steps don’t solve the problem or the root cause remains unclear, turning to an automated PC repair solution like [d1] can help. It can scan for deeper system issues affecting login mechanisms, repair corrupt components, and restore proper integration between OneDrive and your Microsoft account.

Fix 1. Confirm you're using the correct account

Error code 0x8004de8a often appears when the account used to sign in doesn’t match the one linked to OneDrive. This can happen after a password change or when switching between work and personal accounts.

• Check which account is currently signed in.
• If the wrong account is being used, click Unlink this PC and close OneDrive.
• Reopen OneDrive and sign in with the correct Microsoft account, making sure to use the right credentials for either a personal or work/school account.

Fix 2. Reset OneDrive

• Press Win + R on your keyboard.
• When the Run window opens, copy and paste the following text into it:
  %localappdata%\Microsoft\OneDrive\onedrive.exe /reset
  (Note: you might get an error here. In that case, use %programfiles(x86)%\Microsoft OneDrive\onedrive.exe /reset or C:\Program Files (x86)\Microsoft OneDrive\onedrive.exe /reset instead)
• Press Enter or click OK.
• After this command is executed, the app should be reset, and OneDrive should open.
• If it doesn't, wait a few minutes, then open the Run window again and use the following command:
  %localappdata%\Microsoft\OneDrive\onedrive.exe
• Press Enter.
