Entourage: where do messages ago when they are not sent?

[c12281]

Hoping you can help. I spent a long time composing a message, selected the address and hit send. Got an error message stating the message could not be sent because of a punctuation problem with the e-mail address. I realized I did use a bad address, however, I CANNOT FIND THE MESSAGE ANYWHERE. It is not in drafts, inbox, sent or anywhere else that I can find. It was a long message that took a long time to compose. This happened to me one other time, and I rewrote the message a few times until I finally figured out which address was causing the problem. Once I corrected it, the message was sent 5 times! So apparently, the message is stored somewhere. Last time the message was easy to remember. This time, it is not. I'd like to retrieve it so I can just send it to the correct address. Can anyone tell me where the message may be hiding? Thank you so much.

Outbox? It's the location a message goes between sent and drafts
