I'm pleased to update ya'all.
I fimally sorted my problem by posting on the virgin email newsgroup and an engineer foned me back within two days and told me it had been fixed, I opened outlook while he was on the fone and used the new password he gave me...It worked straight off...thankyou Mr Techdude..I knew it wasnt me and its fixed at last..
Thanks to all the contributers who posted in this thread and gave me the idea to contact techs via the newsgroups..I can vouch for its effectiveness and highly recommend it.
