MS Outlook <=> KMail/Evolution/??

Has anyone easily converted back and forth between Outlook and any format readable by a linux email app? I've found a few websites that will probably help, but none seem too reliable.

Back after spring break.. Test and a paper due on friday, so minimal programming will happen, but Multi-CMS has been coming along nicely.
