    Follow these steps on the Windows device to troubleshoot access to a school OneDrive account:

    1. Confirm the correct account type
      • Error messages like “unexpected error” or sign-in failures can occur if a personal Microsoft account is used instead of a school (work or school) account.
      • Sign in to the school account in a browser first (for example, via Office 365) to confirm the account is active and working.
    2. Check which account OneDrive is using
      • Select the OneDrive cloud icon in the notification area.
      • Open Settings (or Preferences) and go to the Account tab.
      • Verify that the listed account is the correct school account. If a personal account is shown, remove it and add the school account.
      • If there is a mismatch between personal and school credentials, this can cause sign-in errors such as those described for codes 0x8004de85 or 0x8004de8a.
    3. Make sure OneDrive is fully set up
      • If OneDrive has not been set up completely on the computer, setup-related errors can occur (similar to error code 0x8004de90).
      • Press the Windows key, search for OneDrive, open it, and complete the setup by entering the school email address and signing in.
    4. Update Windows and OneDrive
      • Install all available Windows Updates from Settings → Windows Update → Check for updates.
      • After updates, run %localappdata%\Microsoft\OneDrive\update from the Run dialog and double‑click OneDriveSetup.exe to ensure the latest OneDrive client is installed, as described for other OneDrive error scenarios.
    5. Reset or reinstall OneDrive if errors persist
      • If OneDrive continues to show unexpected errors, reset or reinstall it. Resetting/uninstalling does not remove files from the cloud.
      • Uninstall (where allowed) via Settings → Apps → Apps & features → Microsoft OneDrive → Uninstall, then reinstall using the Microsoft OneDrive app download and sign in again with the school account.
    6. Check for organization limitations
      • If the school tenant does not support OneDrive for some accounts, sign-in can fail (similar to error 0x8004ded2). In that case, contact the school’s IT administrator to confirm that the account is licensed and allowed to use OneDrive.

    If the problem continues after these steps, provide the school IT support with the correlation ID, timestamp, and error code so they can check tenant logs and policies.

    Hello 서민성,

    The error message does not provide much detailed information. However, since you are unable to access your OneDrive account, please help to check the following:

    • Confirm whether the account has been assigned a valid Microsoft 365 license (including OneDrive).
    • Confirm whether the account is newly created, as this issue can occur if the OneDrive storage has not yet been provisioned. If so, please try accessing OneDrive via https://portal.office.com, then sign in with your account and select OneDrive

    In the meantime, please try the troubleshooting steps below:

    1/ Please try accessing OneDrive in an Incognito/InPrivate window first to check if it works there

    2/ Reset OneDrive

    Resetting OneDrive can resolve many sync or sign-in issues.

    3/ Remove cached work account credentials

    Corrupted credentials can prevent the account from being added

    • Open Control Panel
    • Go to Credential Manager
    • Select Windows Credentials
    • Remove entries related to:
      • OneDrive
      • MicrosoftOffice
      • ADAL
      • AzureAD
    • Then restart the PC and try signing in again.

    4/ Remove the old work account from Windows

    Sometimes Windows keeps a cached work account that causes sign-in conflicts.

    I hope this information helps. If you have any additional questions, please feel free to let me know.
