I'm using Outlook 2007 with Windows 7. I've got several e-mail accounts set up, some IMAP, some POP3. Each account has its own Sent Items folder. When I send messages, Outlook seems to put them in one of these Sent Items folders at complete random. I can't work out what determines which folder the message goes into. Often it's the wrong one, and I spend time looking for a message that isn't where I expected it to be. I also have to periodically sort the sent messages out into the right folders.

I would have thought that if it's a reply or forward, it should use the account that received the incoming message, unless I specify to use a different account to send it. If it's a new message, I would have thought that it should use the account that I select to send the message. But this doesn't always seem to be the case.

What's going on? How does Outlook decide where to put sent messages? What procedure do I use to make sure that sent messages go into the Sent Items folder of the account they're associated with?

Thanks - Rowan
