I found a software conduit that allows the ease of synchronizing your contacts stored in outlook 2007 Business Contact Manager (or BCM as known to many).
You can download the 14 days trial version of companionlink 2.0
After installation, the setup will run where you can change the synchronization configuration of your desktop manager to sync the Blackberry with the BCM folder.
Subsequently, each time your start desktop manager, it will call the 'add on' which is the companionlink conduit and it will sync very nicely. You can even select multiple folders, their sub-folders and others!.
when I'm free, I'll upload a step by step guide of how to set the configuration at my blog here
My setup is a Thinkpad X60 with MS Outlook 2007 w/BCM, blackberry 7100v, Desktop v4.2.1, handheld v4.1.
