Hi Andrew_Smith,
Thanks for your private message. Please do not PM forum staff unless you have been specifically asked to do so. If you require an update, pop a post on your Community thread so any member of the team can pick this up to help 🙂
Taking a look at things this morning, all the email addresses are assigned to your current active Virgin Media account so you should be able to use them.
You can check by signing in to My Virgin Media using the primary account details and then navigate to: My Profile > Manage accounts.
If you need further help, pop back here and let me know.
Thanks,
