Moving EMail from PC to Mac

[cindycat]

I just installed Zimbra Desktop 2.0.1 because I was told I could use it to move all my old emails (3000 or so in 25 folders) from Outlook Express 6 on my PC to Entourage 2008 for Mac on my new Mac All-in-One.

We have two email accounts of the POP type. I'm familiar with setting up the email accounts when we've bought new computers, so I'm not totally illiterate. However, I'm a little reluctant to start this until I know for sure how it will work.

Will I also have to install the program on my Mac? I see there's a Mac version. Other than that, I'm not even sure what I want to ask. I hope there's someone who can help me get my brain around this.

Thank you!
