Hi Axs,

Thanks for reaching out to the forums. We recommend requesting a call from support. They will be able to look into both gamertags and see what the issue is.

Thanks,

Hey there, Timothy Zebrov

Welcome to the Microsoft Community.

Please can you answer the following questions:

1. How long since did you last sign into your Microsoft account?
   
2. Did you have any subscriptions active on your Microsoft account?
   

When reading your post, the first thing that jumps to my mind is that your Microsoft account was closed due to inactivity. This article explains when this happens: Check if your Microsoft account is closed - Microsoft Support

This would explain why, when you tried to sign into your Microsoft account, it told you it didn't exist. Creating a new account with the same username creates a new Microsoft account with a new Xbox account attached to it.

I am not sure if Xbox Support will be able to attach an Xbox account to a new Microsoft account. You can try them by going to this link and contacting a Microsoft agent: Contact us | Xbox Support

Hope this information helps,

Nathan

To confirm: you're wanting to change the email address (Microsoft Account) associated with your Xbox Live profile?

In which case, everything remains associated with the Xbox Live profile (purchases, gamerscore, game history, friends, current subscriptions and so on), it's just the underlying MSA (Microsoft Account, the email address) which gets changed.

However, the funds remain on the old MSA so do not get transferred to your new one, so this will no longer be associated with your Xbox Live profile. The funds should remain accessible on the current/old MSA, but do no transfer across along with the Xbox
Live profile.

Let us know how you get on and/or you have any further questions.

when i sign into Microsoft account, it says "this Microsoft account is associated with a different Xbox live profile. Try a different account."

i deleted my profile, rebuilt the profile, and it didn't help. got the same message.
