Multiple gamertags under one email?

Hey DU5KIE,

Looking into those accounts, it looks like only two have the same email address linked to them. To get the email changed, I would suggest giving

Phone Support a call, and have them switch it for you.

Let us know how that goes, or if you have anymore questions.

So i sign in under the email. How do I access each individual gamertag if they're all under the same email?

Hi there. What this sounds like is all of the "said" gamertags have the same 'Contact Preference' email associated to them. OP - what I suggest you do (if you can) is sign into each account here on xbox.com, then view the profile and see under your avatar
a list of options, one being 'Contact Preferences'. Select this option and from here change the email address shown in the box.

I had a similar issue with emails for my account but it was not because of a name change. It takes some time for the system to update to changes. From what CS told me, 2 weeks to a month. But you should probably contact CS by phone. They told me the
system is not designed to have multiple accounts using one email unless they are a family plan. It could actually corrupt a gamertag account and make it unusable. This is of course just what they told me. I don't know the facts. However it might be a good
idea to call and explain the situation to them.

Make sure that email#2 is not logged in on any devices as a Microsoft Account except on your Xbox console as it may automatically generate a gamertag. After moving the gamertag under email#2, you can contact Xbox Support to check if there is no more gamertag
under email#2 so you can proceed moving gamertag under email#1 to email#2.
