Change email address to another with an closed apple id account
In the past I'd created an account for Apple (account 1), then I forgot the password and the account kept like that for years then made another account to use Apple products.(account 2)
Recently I've closed the account 1 on my email and the account 2 I've used I want to change the address to the email were was the account 1.
At the moment of changing it the following message appears, I think shouldn't be a problem if on that address there is no Apple account.
Hope community can help me
Thanks in advance
