Hi GVB80
Welcome to the Community Forums.
Sorry to hear of your concerns with your wife's email.
Our email service is only available to customers with an active broadband account, and the email must be linked to the broadband account.
Do/Did you see your wife's email linked to your account in your online account management at all? If your wife's email was linked to a previous account taken out, and a newer account was made thereafter when joining back with us, then it would not be linked to the newer account, and should have been removed after 90days of the accounts' disconnection.
If that does not apply in your instance, could you please be able to advise what happens when you try accessing the email?
Do you get the same error when accessing the email through our webmail service or just when accessing an email client like a mail app, Gmail or Outlook service?
