pc xbox gamer tag problems

Hi Colin!

You might have used a different email to sign in to your Xbox app on PC.

Please double check that on your console.

Press the Xbox button to open the guide.
Select Profile & system > Settings > Account > Sign-in, security & PIN.
Under Show on Home, you'll see the email or phone number you use to sign in. If you enable this setting, this account info will be displayed on your Home screen.

Good night. Go to xbox.com account settings and try change the gamertag. If the problems persist contact the support of youre area.

Please don't make duplicate posts. I've already answered you here -

If it says the tag is not available then it's not available.

Gamertags are used on other services,not just xbox live.

Both Onyx and I are xbox ambassadors, and we do not work for microsoft in any way. We are gamers just like you that try to help others. Most of the time, on these forums, you will get replies from ambassadors, and most of the time, what those ambassadors
tell you, is what needs to be done. While I understand you are frustrated, please understand that we take time out of our own lives to try to help others resolve the problems they are having. You might get a reply from Official Support, if they have ideas
they think might help, that an ambassador has not already suggested. But at this time, I believe that what Onyx has told you, calling phone support, is really the best bet at getting this resolved.
