I've also just switched to a MacBook, only because there was MS Office for Mac, but the Outlook is useless because the junk mail filter simply is "junk!" I've tried importing from my old pc Outlook, creating new blocked senders, and nothing works. AND... they just releases an update for Office for Mac 2011 and never even mentioned the problems with junk mail filter. If anyone has any ideas, I'd certainly like to hear them. Otherwise, I'm off to use Mac Mail, where the junk mail DOES WORK!!
