More likely you are no longer a VM Broadband customer and as a result the email account has finally been closed.
That said there are several posts today reporting similar symptoms. A forum team member will respond in a week or so.
_________________________________________________________ Graham I am a VM customer. There are no guarantees that my advice will work. To say thanks click the kudos thumb. If I have solved your problem please click the helpful answer button.
Apologies for your current issues with email, I shall do my best to help
Firstly, if are a current customer and pay for a broadband service with us, please access My Virgin Media and change the password for the email in question (My Profile tab > Manage Accounts).
If the above is not possible because My Virgin Media is accessed by the email address you're having problems with, or, if you are not a paying VM customer, please reply to my PM (purple envelope icon, top right of page) and I'll see what I can do for you.
Hi. I am having the same problem. I have not been able to send or receive emails since the 1st May. I just get told that my username or password is incorrect and when I put in my security question answers I am told that they are wrong. Please advise how this can be fixed. June
