Minecraft login can not use my new email address(account)

Hi! My name is Kyle and I'm an independent advisor.

Where are you trying to log in specifically? You should see a back arrow and/or a button that says "Sign in with another account".

Thanks,
Kyle

Sorry but my English sucks.

how to change email address

Basic steps are to add the new address

Make sure it is there

change new address to primary

login make sure its good

remove old address

So, If I'm understanding your question, you have a gamertag tied your dad's email address that you want to tie to your email address instead, right?

In theory, as long as you have access to both accounts, you should be able to change the associated email addresses(s). You'll need to login to your old Microsoft account (dads) and change the primary email alias to the new email address you want to use.
Before you can do that, you will need to login to your new account (with the email you want to use) and change the primary email alias to some other email account you have. Then, have your dad login to his account and change the primary email alias to the
email you want to use instead. He would be forfeiting his account to you, but that is the only way to keep the old gamertag with your new email address. Keep in mind, if he is the primary account over a family of Microsoft accounts, this would transfer everything
to you... in theory.

It sounds like the email you are recieving mails to is your contact email address. This can, and in most cases, be different to your login , or Microsoft Account, email address.

So logging in with that email has actually created a new profile specifically for that email address.

Do you have any other email addresses you use? You can try sign in with them to see if they log into your account.
