How to open old gamer tag that says offline on Xbox series s if I'm using my New gamer tag?

But if I use the old Xbox (hard drive full). Can I log in with my gamer tag on the old Xbox and delete the hard drive then install only the games I want to play offline.

Will that affect the new series x Xbox ( as I only have the one gamer tag).

If deleted old games from old Xbox, when I log in to new Xbox, will they have been deleted from that Xbox as I don’t want to loose them as I play online on the new Xbox.

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?

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???

You had to have used a different email for the new account. Its simply not possible to have two accounts under the same exact email.

If you tried it would say the account already exists

again: i want to use the NEW GAMER TAG connected to my OLD LIVE ID but with REWARDS OF THE NEW GAMER TAG.
