How to change Xbox email to new one when I don't have access to old email?

Hello, first it's a pleasure to be able to help you today.

My name is welcome to the community.

Hello JustinAppleton, what you want to do is an Alias exchange, but to get to do this you have to have access to the account.

Only after you have access to the account will you be able to exchange the "Alias" (e-mail) for which you want.

I need help i changed my email to my xbox account but its still sending all my emails to the old one and it shows the the old as my email instead of my new one on games and when i register for things how do i change this??

I have a problem like that but when I changed my email the first time 3 years ago I had access to my old email but after it sad i changed it to the new one it didnt. I closed my old email account and I got screwed by xbox live.now there are 3 years worth
of promotions in a email that doesnt exist for my profile. xbox screwed me.

Hello

I am thinking that it is more an account problem than the game since the old email account I had, I do not have access to it anymore and it tells me that that account doesn't exist when trying to log in, note that I changed the name of that email and I have recovered it but I put the changed name to the new primary domain and deleted the old one, that's when I stopped receiving emails so I close that account. however, I don't know what i did when i tried to sign into halo that i get that error and said that the old account doesn't exist, tried to create a new one with the same name as the old accounts but it tells me that its in use. So I don't know what to do. Is there a way that Microsoft can delete those old emails from their servers?

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?
