Is it possible at all to sync another persons private/persoanl contacts (not your own) to the Blackberry . So far Ive heard that its not.
We are on Exchange, BES, Blackberry device is 8700.

No...you can't do this. Each device has a unique encryption key which it associates with your email account. You can only synchronise public folder contacts and your own.

That's not correct. If you have access to contacts (or calendar, tasks, notes) in another user's mailbox in Exchange then you can sync it as a secondary folder. Our executive assistants are all set up like this with access to their exec's calendar, contacts, etc.

However, you must sync via USB. Wireless sync can't be used with secondary folders. Also, all items will appear together on the BB as it won't create separate icons for the two contacts folders. I honestly have no idea how our executive assistants can tell the difference between their items and their exec's items. I'm not entirely certain but I think that the secondary folder is only a one-way sync as well.
