I too have been locked out of my mail account for over 48 hours. I do not use "other devices" and rely on this email for many personal and business contacts, including ebay, and not cannot get emails from ebay either. I am furious and have been on the phone with every conceivable mac help person, and no one can do anything until they send me a password reset (48 hours). Of course I can't get into my mail program to get the reset email, so had to talk to 2 other mac help people to get them to use another email account in order to get the password reset. Supposedly they think my Itunes security was breached which is ridiculous because i don't use Itunes. They are incompetent fools if they think they can cover up their mistakes by saying things like that.
I have had this mac mail account for over 10 years but no more. This kind of thing used to happen more frequently years ago, but in the past couple of years it had not happened, but now this is absolutely unacceptable. DOES MAC EVER EVEN READ THESE ISSUES OR ARE WE JUST SPITTING INTO THE WIND, as they say? Sorry but I can't even tell you how angry I am. Will not be renewing my mac mail account ever.
