We have a Blackberry Enterprise Server, about 50 Blackberries, and Exchange 2003 with a Global Address List (GAL) set up with all the company's shared contacts (several hundred of them, or maybe a thousand).
Right now each person's Blackberry is only syncing with their personal contacts list in Outlook. Is there a way to sync (ideally both read and write) the shared contacts folder? Best of all, it would be nice if each contact could be designated as personal or shared, so personal contacts don't pollute the GAL.
I don't think there is a way of doing this. Out of the box BES will not sync GAL to devices, you can buy third party software to do this (http://www.connectedsw.com/Overview/57261).
There is also the method of manually exporting the GAL to CSV and importing it into each users contacts. I wouldn't recommend doing this though.
Is there a reason that doing an address lookups on the device isn't sufficent? I know for me personally I wouldn't want 100's or 1000's of contacts I never email in my address book.
