Recovery in Exchange

My small business server can’t start it has some files corrupted and can’t even start from the last known good configuration.

I have reinstalled Small business server on the other partition of the hard disk.

How do I

1. Recovery my Shared address book from exchange.Don’t have a back up but I can copy files from the original drive.

2. How do I copy the individual mail boxes.
I have already created the users on the new partition with the same user name, pass word. The server also hasthe old domain name.
