Hi @jameshelm,
Welcome to our Community Forums and thanks for posting.
I am sorry to hear you are unable to access your email account.
The advise given by @Graham_A is correct.
You would need to have an active residential broadband service with us to use our email services.
If this agreement ends, your right to use that email address will also end. The mailbox is usually deleted within 90 days.
Please see our acceptable use policy for more detail on email address usage.
