My GMX email no longer exists?

My GMX email just doesn't work anymore, I created it for my Minecraft account a few years ago.
I don't know exactly what my password is because it's been 1-2 years since I logged in. But I think I know the password because I used to always use the same password.

In any case, I have now tried to reset the password, but there comes that this email does not exist. But if I create an e-mail with the name that I used for my MC account, it means that the e-mail already exists.
So something is wrong, these statements speak again!
Please I need help because the MC account is very valuable to me and I can no longer change my PW because I just can't get into the email!

Gmx automatically deletes mail accounts if you have not logged in once every 6 months. You will receive a message to the account before the deadline to log in again. If you fail to do so because the emails have not been forwarded, the account expires.

Are there any ways to get the account back once it expires though?

Yes u re-create after certain period of time with the exact same name you used i do that all the time 👍 it might say its taken if u tried that right after gmx disabled account so you just need to wait. That how i re-created my old emails 🤣 idk i just hav so many.

Ah i see u already tried to re create maybe u used an alternative email to recover gmx email? Always use a recovery email

Yea gmx will say that email already exist but you need to wait a bit unless it already another few months after deletion of that gmx e- mail… Or was it the same name you used in e-mail is available after a year hmm i have to check out trying to help 😵😆
