You don't say which version of Outlook.
I can't really help as I don't (yet) have a Mac, but try some of the info on
http://www.slipstick.com/outlook/mac.htm
There are some ideas at

Checkout the "User Tools" at

There is a proper imp/exp tool at
http://www.littlemachines.com/
but it'll cost you $10 - considering the hassles otherwise,
it's probably worth it and that's the way I'd go.
