How do I sign into my Xbox account using my new email?

I want to switch the email from my older more used account, to my newer email, but I cannot seem to do so, since a Xbox account has automatically been created. How can I delete the Xbox account from my new email, so I can use my new email to replace my old Xbox account? (This whole thing started with me not being able to sign into my EA account, cause my Xbox account was signed into an older email.)

You cant. The Microsoft account IS the Xbox account. They are all one in the same.

I recommend you wait for the established deadline before removing so you don't have the risk of losing anything

Follow the steps on this page to change the Microsoft account email address or phone number (also known as account alias or username) that you use to sign in.
Worried about your licenses? Don't worry—if you change your account alias or remove an alias and add a new one, all licenses linked to your Microsoft account will remain with your account. Log into your account using your existing alias and password.
Login to your account
Access Your Information at the top of the page.
Select Manage how you sign in to Microsoft.
You may be asked to verify your account before making changes. Follow the instructions provided to select your alias:
Select Add email. You can create a new Outlook.com email address or add an address you already have. Then select Add Alias. After returning to the previous screen, select Verify and follow the instructions provided.
Or select Add phone number. Enter the phone number you want to use and select Next. When you've added a new phone number, we'll send an SMS to that number to verify it. Enter the code in the SMS and select Next.
Note Email addresses and phone numbers that are already aliased to another account cannot be used. It may take up to 48 hours for the change to be implemented across all Microsoft services.

I hope I helped and see you soon.

Hello Sir,

I did do this but my issue is that the account stuff has not fully transferred over. Should I remove the old Alia’s? I am worried since it is my fathers work email and he does stuff with Microsoft and I do not want to delete everything he has

I sign in to my regular account when I sign in on the same email device, but when I log in with the same mail as XBox, a different account appears. How do I replace my new account with the account on my device?
