Hi Ivan Lee
Welcome to Microsoft Q&A Forum. Thank you for reaching out and sharing your issue.
Running into the 0x8004DEED error sounds definitely frustrating.
Based on my research, this error is typically related to network or sign-in issues. While it's not officially documented by Microsoft, others in the community have run into similar problems. I recommend reviewing the links below, as they cover most related scenarios and include suggestions that may help resolve the issue:
Furthermore, here are a few suggestions you can try (if you haven’t already):
- Clear Cached Credentials: Open Credential Manager from Control Panel > go to Windows Credentials and remove any entries related to OneDrive or Microsoft Office > Restart your PC and sign in again.
- Reset OneDrive manually: Follow Microsoft’s official steps
- Check if the account is active and properly licensed (e.g., Microsoft 365 Business Premium or E3)
If it's still not working, your account may be restricted or throttled, this can sometimes happen due to security or usage policies. In that case, only Microsoft Support can remove the block.
- For Personal Accounts: Sign in to onedrive.live.com > click the ? icon in the top right > select Contact Support
- On Windows: Right-click the OneDrive icon in the system tray > Help & Settings > Get Help
- For Work/School Accounts: Go to the Microsoft 365 Admin Center > Support > New service request, or visit support.microsoft.com/contactus (If you’re not an admin, contact your IT department for help).
Quick Reminder: Microsoft’s support starts with a virtual assistant, but if you respond "No" or "Talk to an agent", you’ll usually be connected to a real person after a few prompts.
I hope the details provided will assist you effectively.
