Outlook uses a proprietary archive format in the form of .pst files.
Luckily, some good folks have written a program called readpst which does all the hard work for us. It's available in the LM software manager.

explains the process quite well.
They use 'readpst -D -M -b -o destination_folder Outlook.pst'
however I find it easier to exclude the -D argument because I'm not interested in deleted messages.
Anyway, what you'll end up with is a nice folder structure which mimics the original pst file it came from.
Next, it's a simple import into claws mail and you're all set.
Freedom at last !
