Thanks for your post and welcome to the Forums. It's great having you on board with us in the Community.
I'm sorry to hear that you are having an issue with your blueyonder email account.
Removal of the account is something we can look in to for you but before we can do that I will need some information from you. I will also need to go through security. I have sent you a private message regarding this and will investigate further once I receive your reply. Just click on the little plum envelope at the top right hand side of the page to access your inbox.
