I can't change my gamertag, it says "This gamertag isn't allowed. Try a different one."

Thank you very much. Seriously dude you're the best

Hello Kronos_027, I hope everything is going well!

Thank you for reaching Microsoft Xbox Forum support.

I am very sorry to know you are having such conveniences. Please do not worry about the situation because I am here to help you out!

According to the explanation you have provided, I believe your console might need either a network reset or just a system refresh. Therefore, you will only need to follow those simple troubleshooting steps that I will provide you with and your issue should be fixed.

The following troubleshooting step will help you clear out your MAC address:

Settings > Network Settings > Advanced Settings > Alternate Mac Address > Clear it and the console should restart. It would definitely help if you could restart the internet router while the console is restarting.

Another step that you can try to resolve the issue, would be to remove and re-add your account. In order to do that please go to: settings> account> remove accounts> remove your account.

Note => Please make sure that you remember the password for your account because you will need to sign in again.

If the issue still persists after going through the troubleshooting steps mentioned, I invite you to perform a quick power cycle by turning off the console and then unplugging all the cables. After 10-15 seconds plug all your cables back in and then restart your console.

In case the issue still persists, the next step would be to perform a reset on the console. To do so you will need to follow the steps below to perform a reset on the Xbox :

Settings > System > Console Info > Reset This Xbox > Reset and Keep my Games and Apps.

Note =>The "Reset and Keep my Games and Apps" option will not cause losing your games, but please be aware that you need to be completely aware of the email address as well as the password of your account before going for it because it will require you to sign in to the account.

I wish you a lovely day, and I hope this helps you out! All the best!

Kind Regards

Stay safe, and happy gaming

[quote user="Running Pubs"]I am trying to change my gamertag to something different. But when i go to change my gamertag, it says the gamertag I want i "already taken"

But when i go to send a message to the gamertag, it says it doesn't exist on XBOX LIVE. [/quote]

If the name change attempt tells you the gamertag is taken, it is taken. What's probably happening is that there's a difference in the spacing: I can't change to
RunningPubs because you are Running Pubs (with a space), but trying to send a message to
RunningPubs would fail because that variation isn't the one in use.

(I suppose you're trying to "purchase" a gamertag change, but these questions usually go in "Managing My Account", where there's a sticky post covering exactly this issue.)

But the gamertag that I want to change is my old gamertag. I change my old gamertag on 2 August 2020. I used that old gamertag when I create my Xbox account. At that time, the system allow me to use that gamertag. But when I want to change it back, the system don't allow me to use it. Why is this like that?

Hi! My name is Pam. I'm an Independent Advisor and I'll be glad to help you today.

I'm sorry to hear that. Please don't get me wrong but I'd like to be honest with you that there are certain reasons as to why it isn't allowed and it's the enforcement team who decides. Most likely, a letter combination is not allowed or it's a gamertag of a banned account. I hope you understand.
