Wait!!! Can I jump in this thread? My Dell desktop with Vista and Office 2008 cannot send or receive email using my Yahoo.com address, even though I've entered the incoming and outgoing info and password correctly. I tried to download the above 64 bit site, but after completing the download, it told me that this download did not apply to my computer. Have I missed something? Here's one more possibly valid point: On my account settings for the Yahoo account, I've changed the incoming and outgoing numbers correctly. However, I see that under the Account Type, I think I need to change this to "POP3". But it's greyed out with "IMAP" in there and I cannot change it. Is this where the problem lies? Thanks a mil!
