Ok, that screenshot shows that you are currently logged into a VM webmail account to which you have added two additional blueyonder email accounts.
In order to check the individual blueyonder email address your first need to click on the hamburger icon to the left of the virginmedia infinity logo and select 'sign out' under the list of options.
Once signed out go to https://mail2.virginmedia.com/ and sign in with the blueyonder email address and password.
What, if any , error message do you see?
