Facing problems in migrating mails.

Question

Hello,

I am into event organizing and receive a lot of mails daily. Recently i have switched to windows laptop using Outlook 2010 as my email client. Earlier I used Mac with entourage 2008.

All I need is to move all the emails from Mac to Windows.
I have been trying Imap account transfer but its a little time consuming.

Can anyone suggest any faster and accurate solution, will not mind spending some bucks if necessary.
Thank you
