Question details

The user needs to migrate a large volume of files to a new Microsoft account because their old email address is inaccessible for receiving security verification codes.

How to Transfer OneDrive Files When You Cannot Access Your Old Email

Product: Microsoft OneDrive
Device & OS: not provided
Scenario: Migrating files from an old Microsoft account to a new one when email verification is blocked.
Observed behavior: The user can log into the old OneDrive account but is blocked from updating account security info because Microsoft sends verification codes to an inaccessible, defunct email address.

Before you start

Ensure you still remember the login password for your old Microsoft account, as you will need it to authorize the file migration to your new account.

Solution 1Recommended

Use the Microsoft Mover Transfer Wizard

This is the most efficient method to migrate large amounts of data (such as 500 GB) between cloud accounts without having to download everything locally.

Microsoft provides a free web-based tool designed specifically for migrating cloud data. As long as you can log into the old account with your password, you can use this tool to copy files directly to your new account.

Access the Mover tool

Navigate to the Microsoft Mover login page (app.mover.io) in your web browser and sign in with your new Microsoft account.

Authorize the source account

Click 'Authorize New Connector' under Step 1 (Select Source) and log in using the credentials of your old OneDrive account.

Select files to transfer

Once the old account is connected, browse and select the specific files and folders you wish to move.

Authorize the destination account

Under Step 2 (Select Destination), authorize your new Microsoft account and select the folder where you want the transferred files to be saved.

Start the migration

Click 'Start Copy' to begin the transfer process. You can review the migration report afterward to ensure no files were skipped.

Account Verification Blocks: If Microsoft's security protocols strictly lock the old account and demand email verification during the Mover login, you will need to contact Microsoft Support directly for an account recovery.

Solution 2

Manually Download and Upload Files

A fallback manual method if third-party migration tools are blocked by Microsoft's security prompts.

Frequently Asked Questions

Will the Mover Transfer Wizard delete files from my old account?

No, the Microsoft Mover tool only copies the files from your old source account to the new destination account. Your original files will remain safely in the old account unless you manually delete them.

Can I simply merge my old Microsoft account with the new one?

No, Microsoft does not currently provide a feature to merge two separate Microsoft accounts or their associated cloud storage directly. You must manually transfer the files or use a migration tool.

What happens if I cannot remember the password to the old account either?

If you do not have the password and cannot access the recovery email address to reset it, you must fill out the Microsoft Account Recovery form to prove your identity and regain access.
