1st attempt:
Got through to a very *unhelpful* tech support bloke first, but just promptly thanked him for being no help help whatsoever, and then redialed.
2nd Attempt:
Got through to a very helpful person, Pete - so thanks Pete.

Who suggested the work around they have currently.
Let them set up the email account names for example
email.account01@ntlworld.com through to
email.account11@ntlworld.com
Then you can go in an modify them. Make sure you get them to set up all of them.
So that's what I done, then went make and modified them and the passwords to what I wanted.
Not Ideal as they have sold us a package where we are supposed to be able to create and delete our own email accounts, I thought.#
Hope it all helps.
