Sending, receiving, and organizing email in Outlook.com
Hello, unfortunately, there’s no way to transfer your Xbox profile, including your Gamertag, progress, and purchases, to a different Microsoft account. It’s permanently linked to the one you originally used.
The best workaround, even if it’s not your favorite, is to add your new email as a sign-in alias on your current account and then make it the primary address. This lets you stop using the old email without losing any of your stuff.
If you really want to separate things completely, you’d have to create a brand new Microsoft account for gaming, but that means starting from scratch. You can use “Home Xbox” game sharing to share games between accounts, but your profile and game history won’t transfer.
