We have recently had to reinstall a very unhappy Exchange 2003 server for a client, and whilst rebuilding their server we moved them onto a temporary one.

During the course of all this, ExMerge was used due to Windows being so broken that none of the backup software could run. As a number of the user mailboxes were way over 2GB, we had to do date ranges of a few months at a time to avoid ExMerge's 2GB limit.

We went back as far as 2006, as the files produced by ExMerge seemed empty that far back.

Unfortunately, one of the users has reported that around 2 3rds of their contacts are missing, and that pre-2006 sounds about right for the missing items.

Is there any way I can mount the old EDB file into Exchange, or otherwise read their contacts into a usable format?

The server is running Windows Server 2003 SBS R2 (SP2), and Exchance 2003 (SP2, I think).
