A Microsoft file hosting and synchronization service.
Error code 0x8004deed is not covered in the available documentation. However, similar OneDrive sign-in and access issues are often caused by account, licensing, or credential problems.
Based on the available information, try these checks and steps:
- Verify account and license
- Confirm that the same Microsoft account is used on both the Mac app and the web.
- If this is a work or school account, contact the organization’s IT admin to confirm that:
- The account still has an active OneDrive/SharePoint license.
- The account is not blocked and has access to OneDrive.
- Check for known sign-in issues and updates (Windows scenario reference)
- Similar issues where OneDrive reports connectivity or sign-in problems have been fixed by installing specific Windows updates (for example, KB5085516 addressed Microsoft account sign-in issues caused by another update). On Windows devices, check Settings → Windows Update and install any pending updates that mention fixing Microsoft account sign-in.
- Clear cached credentials (Mac)
- On Mac, remove cached OneDrive credentials:
- Open Spotlight and search for “Keychain Access”, then open it.
- Search for “OneDrive”.
- Delete “OneDrive Cached Credential”.
- Restart OneDrive and sign in again.
- Reinstall OneDrive from Microsoft (Mac)
- If OneDrive was installed from the Mac App Store and fails after an update, uninstall it and reinstall from the Microsoft download instead, as this has resolved launch issues for some users.
- Check service health and web access
- Since the web view shows a blank “My files” page, verify whether OneDrive works from another network (for example, a mobile hotspot) and another browser or a private/incognito window.
- If OneDrive works in another environment, the issue may be related to the current network or local browser cache; clear cache and cookies and try again.
If the account is managed by an organization and the problem persists across devices and networks, escalate to the organization’s IT admin or Microsoft support, as this may indicate an account-level or service-side issue rather than a local client problem.
