Plus one of the question/answers on your above tutorial - how Mary solved the problem:

I have experienced communication problems between Sky email and Outlook 2003 for several days since re-installing Outlook, even though the setup appeared correct, including enabling POP within the Sky.com email settings, and ensuring Outlook 2003 complied with Sky ports, eg 995 and 465 - as shown at the top of this web page. A pop/smtp pop-up kept prompting me for my password. No matter what I did I couldn't get it to work and it was driving me nuts.

EUREKA! I have found a solution after reading the helpful comments by other users, and by trial and error. IT HAS WORKED FOR ME!

I logged into Sky email in the usual way, but DID NOT enter my password. I ticked the "forgotten" box so that it could be reset. I then entered into my Sky email account using my existing password. I opened the Sky reset email and proceeded to change my password. (don't forget to write it down for future reference). I then went to www.sky.com/unlock and entered my NEW password. I received a confirmation message from https://www.google.com/a/sky.com/UnlockCaptcha "Captcha successfully unlocked"

I then went to back into Outlook 2003 email account settings, and entered my new password. I clicked "Test account settings" and at last my OUTLOOK 2003 now speaks to Sky email. All my emails have downloaded to OUTLOOK 2003. A BIG THANK YOU to everybody for posting your experiences, and frustrations.

I hope this helps someone too. Good Luck
