‘please go to mail account settings and enter a password’
That error message suggests that you are using an email app (perhaps on your phone) to manage your VM email. Sadly whenever email apps encounter a problem accessing the email server they often default to reporting an issue with the password.
Sign into your VM email account directly on the VM website from here https://mail2.virginmedia.com/ and post back with the error message (if any) that the VM systems is reporting.
That information will provide a clearer idea of what the real underlying issue is and enable forum members to give you better advice as to the next step to take.
