Unable to recover due to backup is not stored with account.

I recently upgraded to a new phone after my previous device died unexpectedly. I had Microsoft Authenticator installed on the old phone with cloud backup enabled, and more than 20 accounts (personal, work, and financial) were stored in it.

After setting up the new phone and signing into the Microsoft Authenticator app using the same Microsoft account, I attempted to restore my backup. However, I received the following error:

“Unable to recover. Your backup is not stored with <EMAIL>.”

This was surprising because I had explicitly enabled cloud backup on the old device. I’ve confirmed that I’m signed into the correct Microsoft account—the same one used for backup—and I’ve tried multiple times to initiate recovery.

Here’s what I’ve already checked:

• Verified Microsoft account credentials and aliases.
• Confirmed that the backup was enabled on the old phone.
• Attempted recovery using the “Begin Recovery” option in the app.
• Tried accessing backup from multiple devices.
• Reviewed documentation and similar threads, but couldn’t find a resolution. Old phone; Android; Samsung Galaxy S23 Ultra. New phone again Android Samsung phone.

I suspect the backup either didn’t sync properly before the device failure, or there’s a mismatch between the account used for backup and the one I’m currently signed into—even though they appear identical or something strange happened with I logged into account.

I’d appreciate any guidance on:

How to verify if a backup exists and where it’s stored.

Whether Microsoft Authenticator backups are tied to specific device IDs or aliases.

Any recovery options for work/school accounts that were stored in the app.

Whether Microsoft Support can manually retrieve or verify the backup status.

Thanks in advance for your help.
