I just tried what you said... I started my avast! mail protection wizard three times in a roll... nothing happened as you mentioned. I never saw anything like that...
Okay, I will tell you how I managed to do it!
I signed up to my new email account, but kept my user name the same. So without thinking about it too much, I changed the POP3 and SMTP settings in Outlook Express to my new ISP but did not alter anything in the Account Name Field. (I should have removed the #mail.btopenworld.com from the name)
Then I closed Outlook Express and ran the Email Protection Wizard to protect my email account. When I tried to send an email, Outlook Express would not work and I had the same prompt screen as Ringfinger did in his orginal post.
My problem was the Email Protection Wizard had correctly altered the POP3 & SMTP settings to 127,0,0,1 but in my Account Name Field I now had the extra # new mail account. (#mail.btopenworld.com#virgin.net) My new ISP mail details had been added to the old ISP mail details, so obviously my email did not work.
Removing the protection from my account using the wizard did not restore the account either, don't forget originally I did not changed anything in the Account Name Field.
Why did I not use the email protection wizard to restore the accounts in the fiirst place? Good question probably because I didn't know enough about how the wizard worked at the time!
All this happened eighteen months ago, the problem was caused by me, I have had no problems since, all my orginal post was trying to do was help to stop a newbie making the same mistake so please give me a break!
