A Microsoft file hosting and synchronization service.
Open OneDrive in an InPrivate browser window and sign in with the exact personal Microsoft account that owns the files; this distinguishes an account-level access failure from a Windows sync or cached-session problem.^1^
1. Test direct web access
- Open an InPrivate window in Microsoft Edge with Ctrl+Shift+N.
- Go to https://onedrive.live.com and sign in with the Outlook.com account that owns the files.
- Check whether My files opens.
Microsoft’s consumer service-status page currently reports services as operational, so there is no public indication that this is a widespread outage.^2^
- If the files open: the account and cloud files are accessible; continue with the Windows steps below.
- If the same permission error appears: continue with the account checks.
2. Check the personal Microsoft account
Sign in to the Microsoft Account dashboard and verify that the same account works there. Microsoft recommends this as the first check when OneDrive cannot sign in.^3^
Also check:
- Storage: https://account.microsoft.com/storage
- Subscription: https://account.microsoft.com/services
If OneDrive explicitly displays Account frozen, reduce storage below the quota or purchase additional storage. Microsoft states that quota changes can take up to 24 hours to apply; contact support if the account remains frozen after 48 hours.^4^
Do not delete local copies of important files while access is unresolved.
3. If web access works but Windows access does not
This points to the Windows OneDrive client or local file permissions rather than ownership of the cloud account.
- Select the OneDrive cloud icon in the Windows notification area.
- Select Help & Settings → Settings → Account.
- Confirm that the displayed address is the same account that worked on the web.
- If it is the wrong account, unlink it and sign in with the correct one. Microsoft lists unlinking and relinking as a supported sync troubleshooting step.^5^
If only particular local files fail:
- In File Explorer, right-click an affected file and select Properties.
- Open Security.
- Select your Windows user account.
- Confirm Read and Write are allowed; if not, select Edit and grant those permissions.[^6^](https://support.microsoft.com/onedrive/troubleshoot-onedrive-error-this-file-can-t-be-synced "Troubleshoot OneDrive error: "This file can’t be synced" | Microsoft Support")
Avoid changing ownership or granting Full Control unless the failure occurs only in File Explorer and the files are accessible on OneDrive.com; those changes affect local NTFS permissions and will not repair an account-level web permission error.
4. Escalate an account-level failure
If the same error occurs on OneDrive.com in an InPrivate window, contact Microsoft Support using the Contact Microsoft Support option on the personal-account support page.^5^
Provide support with:
- The full error message
- The correlation ID from the error
- Timestamp: 29 October 2026, 14:44:59 GMT
- The affected Microsoft account address, supplied privately
- Confirmation that the error also occurs in an InPrivate browser
Do not publish the correlation ID or account address in a public forum.
