Can anyone point me in the right direction for how to move my email folders from Zimbra Desktop to Outlook 2010?

I have been using the Zimbra Desktop for about 2-3 years now and have hundreds of emails that I have saved in various sub-folders. I have recently purchased a new PC and would like to start using Outlook 2010, but would like to move all my email folders from Zimbra to Outlook. Not sure how to do this.
