KMail mailboxes to Outlook?

All, I've seen discussion of moving your e-mail from MS Outlook over to Linux and KMail. What about going the other way? I have several thousands of messages in KMail that I'd like to have available *as e-mail messages* in Outlook. A change at the company has required that I get rid of my Linux partition and go back to Windows and Outlook. I can use Linux on another computer, but my e-mail is to be handled via Exchange Server and Outlook.... darn-it! I know that I can just move everything over as plain text, but it would be much more useful to integrate all the messages that I've kept in KMail for the past 14 months back into Outlook -- which I was previously using. Hints? Suggestions? /kevin
