Microsoft Account Email

This can only work if your emails are NOT hotmail, outlook or live emails as those are Microsoft email addresses. That may be the cause of your problem. You can not change TO an email that is a Microsoft email. You can change a Microsoft email to any other
non Microsoft email, though.

Please see this page on how to change the emails if you don't have those emails as your current primary ones:

Hi there

Create a junk email address, then create an alias on the email in the account you want to this junk email address.

then make that alias the primary email. This will then free up your email to be used in another account.

Hi, I would refer you to the following
guide for adding and/or removing an email address from your account.

If you're having trouble signing in now in order to make this change, I'd refer to the following

guide for filling out a Microsoft account recovery form and with tips for doing so. If you're unable to recover the account or need additional support, you might

contact Xbox Support directly, though I couldn't guarantee that they can assist beyond the recommendations in the previously-mentioned guides. Hope this helps!
