Solution 1Recommended

Reduce Storage Usage to Unfreeze the Account

The most effective way to restore access to a frozen OneDrive account is to delete unnecessary files and bring your total storage usage below the quota limit.

When an account is frozen, temporary unlocks can sometimes fail with the unlockDriveRootExpired error. To bypass this, you must manually free up space so the account is no longer in violation of the storage limits.

Log in to OneDrive

Open your web browser, navigate to the official OneDrive website, and sign in with your Microsoft account credentials.

Delete Unnecessary Files

Browse through your OneDrive folders. Select large files, old backups, or media you no longer need, and click 'Delete' to move them to the Recycle Bin.

Empty the Recycle Bin

Click on 'Recycle bin' in the left-hand navigation pane. Click the 'Empty recycle bin' button at the top of the page to permanently delete the files and free up your storage quota.

Wait for Quota Update

Allow up to 24 hours for Microsoft's servers to process the storage changes and automatically unfreeze your account.

Storage Update Delay: Even after emptying the recycle bin, the storage quota update is not always instantaneous. Please be patient while the server synchronizes your new storage total.

Solution 2

Contact Microsoft Support

If reducing your storage usage does not resolve the issue or the unlockDriveRootExpired error persists, you will need account-specific assistance from Microsoft.

Frequently Asked Questions

Why did my OneDrive account get frozen?

A OneDrive account is typically frozen if you exceed your storage allowance (such as the standard 5 GB free limit) for an extended period of time, or if you haven't signed into the account for over a year.

How long does it take to unfreeze my OneDrive account after I delete files?

After you delete files and empty the recycle bin to bring your storage below the limit, it can take up to 24 hours for the system to process the quota change and unfreeze your account.

Will I lose my files when my OneDrive account is frozen?

No, your files are not immediately deleted. You simply lose the ability to upload new files, edit existing ones, or sync changes. However, if the account remains frozen for an extended period without resolution, Microsoft may eventually delete the account and its contents.
