Finally moved to Mac, and I'm trying to move about the past 5 years' worth of e-mail from Outlook to Mail.app. I tried the Netscape workaround, but Netscape Composer refuses to import my messages. So far, I've had the best luck with importing my mail from Outlook to Thunderbird in Windows, then transferring Thunderbird's mail folders to the Mac. However, Mail.app won't let me import the Thunderbird files, even after rennaming the extension-less file with the .mbox extension. The file is greyed out in the import window. Any ideas? Any and all help would be awesome. Thanks!
