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.

Thanks,
Mike
