Changed name mistakenly and want my old name back

Sorry to hear, but what's done is done. There is no way to go back to the old system once changed at this point. My best suggestion is to change it to a similar name like "Snoopy Jam" if you want to at least stay within the ball park of your old name or
take advantage of this time to start new. Either way, you will probably be charged for another name change since your sibling used the free name change.

Just recently i changed my gamertag to “do you cuss” thinking it was funny and in the moment it was but now i want to change my name back to what it originally was. I used my free name change to chamge my gamertag, i talked to support and they said
that free items dont appear in the order history. Is there any possible way i can change my name back to my original name that was 15 letters?

You will not get a another free name change once you have used the free one, also you will not get your old name back as the limit is now 12 characters so you will have to think of another name.

Hey there!

Nice to meet you! My name is Christian, an independent advisor. I'm here to help you out.

That's going to be very tough considering 2018 was 5 years ago. Do you still have access to the email address associated with your old Gamertag? If you do, Check that email addresses inbox and look for anything related to Xbox. You should be able to find out the actual gamertag.

I hope this helps.

Best Regards,

Christian.

the email that i used for the account 5 years ago is the account i use to this day. i have access to the email but have received 1000's of emails from microsoft meaning it would take me very long to find emails with the old account name

Try sorting it out starting from the oldest. I know it can be tedious but the answer is contained in one of those emails. Hang in there, Buddy.
