That's unclear. If it's created as you say, apparently it was created, and it should be accessible. it could be that you can't create such email addresses now (do you have a link to some source that says it can't be done), but old accounts should still be accessible.
All you can do: contact yahoo customer service. And don't fall for spammers that trick you into fake support, only to have you pay or install malware on your PC.
I need help creating an email account with the @yahoo.com ending.
My firend created an account in a game with an email address that had two periods in it, for example email@example.com. he then reset his password, and the new password was sent to his email. As of now you are not able to create email addresses at yahoo.com that has two periods in it, therefore he has not been able to access his game account.
Is there any was you could bypass this, by for example creating the email elsewhere, or trick yahoo.com so that you are able to still recieve emails through this email address? I have tried variations of trash mail websites, bt they all use a soecific email ending, and you are not able to use the @yahoo.com one.
Thank you in advance.
