How delete unused icloud mail account from my Apple Account
I recently changed my email address associated with my Apple account and stopped using my previous iCloud account. I tried to delete it and it won't let me, as an icon with a question mark (?) appears. On the web it tells me that that account is an alias of the new one I use and on the Macbook that it is used for Messages and FaceTime. I have checked and it is not defined that account for those services.
Is there any way to delete or deactivate that account?
Thanks!
