I've been using Address Book to access my Exchange 2007 (now 2010) contact list for over a year. It crashed yesterday when I dragged a contact from my Mac (10.6.4) to the Exchange 2010 database. Address Book now crashes immediately after launching "due to uncaught exception…". --- Application Specific Information: abort() called * Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'Unable to process an invalid response from the Exchange server: response set count does not match request size'
i solved the problem by deleting (actually moving) the files in ~/Library/Application Support/Address Book, then restoring those files from a Time Machine backup from the previous day. I may have lost a couple of recent contacts in the process, but it's not the end of the world.
