Is it possible to view all of the gamertags that have been used on my Xbox?

Hello!

I'm a Independent Advisor. I will be glad to help you.

Unfortunately there is no account history entered in the console, if you don't know the email address check the information on this page, maybe I can help you find it:

The possibilities listed there are the only ways you could find the email address.

Best regards

Some gamertags have been used in the past and are frozen for a period of time - the xbox team is working on releasing some of the old ones from the original xbox. You might get lucky - they release old gamertags once in a while. Also some gamertags you cant
use as they are viewed as offensive.

a warning in my eyes for example would be something along the lines of "you have been reported and viewed using hacks, your gamertag will be recorded and permanently banned if a similar violation occurs"

It is possible to have a gamertag with three characters, in fact it's possible to have a gamertag with only one character. The problem you have would be availability. Most (if not all) gamertags less than four characters would
have already been taken by someone else.

It's not possible to request a gamertag to be released. The tag system is in use on other Microsoft services, so even if it's not in use on an Xbox, it may be in use somewhere else. However, there has been a recent update so you can have a gamertag even
if someone else has it. https://support.xbox.com/my-account/manage-gamertag-and-profile/gamertag-updates-faq
