I want to be able to sync my entourage inbox with my blackberry inbox and viceversa.
I'm able to sync the contacts, the calendar, tasks,
But my most important thing is being able to updates inbox in both in the power book and the blackberry,
Is there any posibility to do this?

Using the "Search" button, enter the word "entourage"; you will find everything you need right there. Good luck!

NJBlackBerry's search term is an excellent one -- try it.

Inbox synchronization is probably something that likely requires BES.

You may need to use a Mac-compatible BES hosting service.
