>Hmm... Interesting... Basically what was going on was that I was trying to help out one of our salesmen who was having this difficulty. I think he was using either XP Home or XP Pro (I was hearing rumors that Outlook Express "broke" on XP after a recent service pack). What was really weird is that the messages would move from the "Outbox" to the "Sent Items" w/o actually sending anything! The problem only started after trying to set up more than one E-mail account.
Nope, I use OE on XP with all the latest patches. What's broke about OE is some ability to do cut and paste when you reply to some messages. It craps out on occassion there, but a fix should be available soon, or you could rollback the .DLL that's broke to a previous version. I'm not positive of the name, but I think it's mshtml.dll.
