The verification code always be sent to the unwanted email

My guess is that would be the 2 factor authentication.

There are two things here.

1. The account that you login with

1. The account where the code will go.

You will have to get them both changed with help from the original user. You can change these settings in the Microsoft Account Settings.

Hi there! This is Virginia O.

I understand that you are experiencing issues getting the verification code.

I apologize for the inconvenienced this has caused you. I will do my best to help you.

Please check your email address. Make sure that the email displayed on the verification screen is correct. If you have multiple accounts, confirm that the one tied to Xbox and Microsoft Store is the one you’re trying to access.

And then search your email b looking for keywords like "Microsoft verification code" or "Account security" in your inbox. Kindly check your Spam, Junk, and other folders for the email.

Next is use an alternate verification methods. If you have other recovery options linked to your account, such as a phone number, request the code via SMS.

Or an authenticator app, enable it for verification.

Thank you for your cooperation.

usually verification codes are sent through email or sms. if you can't find it contact support.

Is this a problem with the security proofs? I'd check your email account as quite often a verification code is sent to that

Yes its up to date they even sent me a verification code to email which i recieved but still no email with shipping labels.
