I'd hoped I might have some luck as well, although I'm not that surprised that I haven't. This seems to be a very widespread problem, and not a new one at that - I used to get this with Outlook Express as well. I would have thought by now that someone would have come up with a definitive answer - Microsoft themselves, maybe...?! - but no-one has, or at least no-one that I've yet come across. I must say I'm hoping to find some solution, as I've a number of e-mail accounts, and these messages keep popping up with annoying regularity!
