changing my Microsoft email on xbox one?????

You can not really merge to accounts, but you can change the primary email address on the account your gamertag is associated with to the email address of your newer account.

If you still own a Xbox 360 there is a guide available to bind your gamertag to a different live account, which is much more easier to do, then change the primary email address.

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:

No, the email address I want to use is the new one. I've already recovered my old account (this one) which is the one I want to keep, just attached to the new email address. I've created a new microsoft account and xbox account for the email I want to
use, but when I try to 'Change Microsoft Account' on my xbox it says the email doesn't have an xbox account. But I can use that email to log into the website and can use it on my xbox by downloading that profile.

so... email 1 is used for the "" account, and email 2 is newly set up with "Temporary Placeholder style name" account. I try to Change Microsoft account from email 1 to email 2, but it says there is no account on email 2.

The email on this account is only active temporarily and I am trying to change it to the new email so I do not loose my purchases.

You can't transfer data from one account to another and support will remind you that is against the service rules

In the top right corner of my Xbox it shows an old email I don't want on there and yes I changed the billing and Microsoft email but I can seem to get rid of that old one appearing but when I sign in to my Microsoft account it's still the old email so that
might be the problem anyone know how to change the sign in email for Microsoft accounts?
