Ever tried moving your mail from MS-Outlook to Apple Mail? It's not even supported by neither Microsoft nor Apple. Apple refers to three third-party applications. I tried one - the cheapest. It's O2M by Little Machines but did not work out for me.

What a hassle

O2M is the paid option. It generates MBOX styles mailboxes which you can import directly into Apple Mail. Unfortunately Apple Mail will not set correct headers and time stamps on importing. It will leave your sent-box a mess although this is not immediately clear.

The other - free - option is downloading Thunderbird on your Windows machine and import your Outlook into it. Then you just copy your Thunderbird profiles folder to your Mac and choose import from Thunderbird. Unfortunately this option cannot be trusted neither. Some folders are ignored, attachments as well, headers are incorrect.

Eudora Mailbox Cleaner

Luckilly there is Eudora Mailbox Cleaner to the rescue. It handles more than the name suggests. You can just drop your Thunderbird profiles folder - compact your folders first - onto this wonderfull app and it will correctly import your mail folders and attachments. After having done that, just rebuild every folder in Mail - try applying a short-cut - and you're done!
