Can not change profile address to make purchase.

Your Xbox profile is linked to your Microsoft Account, not to any specific email address. You can change the email address for your Microsoft account without losing your Xbox profile or purchases.

You can't delete a gamertag/profile. If you pay 800 Points to change the gamertag, the old one will be available for a new profile. You can change the Live ID to another email address (that's free), making the old one available for a new profile.

I would check to make sure you upgraded to gold with the correct email address. Normally, your gamer tag won't change when purchasing gold. In fact, you either have to change the gamer tag via an 800MSP purchase, or a forced change from the XBLPET.

I would log into your normal gamer tag on your console and then check to see what the email address should be. In the upper right hand corner of the screen, your gamer tag will roll over to your email address. If it doesn't, then you can change a setting
in your account to get the Microsoft Email Address to show. It should be in your profile settings under 'Show Microsoft Account'.

If that still doesn't work, you can always call support at 1-800-4-MYXBOX, and they can aid you in confirming what the email address for your gamer tag should be.

I hope this helps!

You can have multiple addresses in your Amazon account. When I make a purchase and the AU address doesn't work I just click 'change address' and choose my CA or OR address I have with Shipito. For digital purchases I always use the latter because I wont
get charged sales tax.

Hi SidneyBorjesson

It is impossible to set-up two Xbox profiles using the same email address. So something isn't right here. Profiles are based on Microsoft accounts and these account are not allowed to share the same email address or alias.

Either your brother has somehow managed to change the details on your profile to make it his own or if you say you can still search and find your profile elsewhere, then the only thing I can suggest is that he has managed to change your email address so
he can use it.

I would go and check your Microsoft account details to make sure all is as it should be.
