I have done a quick test and there is no mail undeliverable message being returned to the address appears to be valid.
Sadly, it appears to be quite common for orphan accounts to appear to be valid, as you describe, but actually the account itself is inaccessible. Presumably that is because Virgin Media have closed your webmail account but not the mailbox itself.
If you get the error message "Unable to find your username" that is bad news. However if VM recognises your email address then you have a chance, even if it is a small one. 😯
Post back here to let us know how you get on with resetting the password and whether you have regained access.
If you no longer have a VM broadband account there is very little that VM can do to help you. However, one of the Forum Team (VM employees who support this forum) should contact you via this forum in a day or so and they will be able to let you know the situation with your account.
