Take off my old gamer tag

Thanks, I appreciate you getting back to me but that isn’t helping.

Maybe I’m not explaining this right.

I restarted my console this morning when I signed back in I didn’t read things correctly and used my email and password to sign in and then started with a new gamer tag with the same email as my old gamer tag.

Now when I sign in it’s my new gamer tag that pops up. I tried deleting the new tag off my console and resigning in but again the new gamer tag pops up.

There is no option to look for tags associated with the same email???

All my purchased games and game pass is associated with my old gamer tag. How do I get my old gamer tag back with this email and onto my console???

This is not my real gamer tag my real gamer tag is xXZombiebestXx so this is my old gamer tag

call microsoft and give the the old gamer tag and the them to cut it off.

For some reason my new gamer tag linked itself to my old gamer tag email address. I don't know how to change that and to link my old gamer tag back to my Microsoft account. I believe that's why I cant play as my old game tag. Is there a way to fix that?

Gamer score leaderboard also shows as my old gamer tag above my game points, are these places where my new gamer tag should be on Xbox 1? On my Xbox 360 my old gamer tag is nowhere to be found even if I look for it
