Typed the wrong email address in Minecraft PE and I can’t sign in into another account

Thank you so much! It finally worked!

Hi! I'm Luis, a fellow Xbox Gamer . Thanks for reaching us out here.

Try choosing the AA optionat the top right, then choose the request desktop browser. You should see an option to change account

Here’s the picture of what the screen looks like because for some reason the image didn’t upload

Glad to help! If you don't have any more questions and have a moment to rate my support I'd appreciate it

My son changed the email on our Xbox account. Now I can’t sign into my email account. What can I do to resolve this problem?

Hopefully it wasnt a Microsoft email he removed from the account because per https://support.xbox.com/en-US/help/account-profile/manage-account/change-email-sign-in-for-microsoft-account it says:

"Warning When removing an email alias that’s connected to a Microsoft domain (such as @Outlook.com, @Live.com, or @Hotmail.com), that email is completely deleted from our systems and can’t be used to send or receive emails. It won’t be available for use again as an alias on another account. Microsoft doesn’t recycle email addresses, so it can’t be reclaimed at a future time."

If this is what he did then I dont think there is any way of reversing this once it's been done but someone can correct me if im wrong.
