I agree with Anne. It sounds like this could be a yahoo problem and not an Outlook problem. Since you say you have "other mail" in Outlook, try sending yourself some mail with those accounts to see if they work (first turn off the Yahoo mail, so you can do an accurate test). Test each mail account separately ... That's the only way you can narrow down the problem. If it IS a Yahoo problem, then you need to contact yahoo, becuz they are the only ones who can help you. Also, though I doubt your pst file is the problem, I believe the pst file is now considered a system file in Windows XP, so you need to tell Windows to search hidden and system files in order to find it. But, I don't think you need to do that anyway ... It's sounding more and more like this is a Yahoo problem. Linda F.

Yahoo have tightened up on being able to use Outlook for reading Yahoo mail. I would visit the Yahoo mail help pages and see if you can find any hints there. BTW my settings are for Yahoo.co.uk and I use pop.mail.yahoo.co.uk for incoming and my local server for sending.
