We recently had a big crash on our server and ended up re-installing Windows NT, SBS (including Exchange Server 5.0) and had to create new profiles/mailboxes for all of our users. We managed to recover the old EDB files which we think contain all of our old e-mails and information. Could you please advise as to whether there is any way to retrieve the information from within these seemingly locked database files.

look on microsoft's site for the whitepapers about disaster recovery and exchange - you'll basically have to have another system to work with - you'll need to keep it completely off the network and install exchange AND nt with the same machine name, domain name, and site name - then restore from backup to this "spare" machine - then install outlook and log into each individuals box, export to a pst - and copy it by zip or something to the CLIENT machine, and have them re-import this pst, to their machine - i personally opted to tell them when our machine went out that the backup fried, and saved myself a lot of pain - but we don't have much info and they had extra copies anyway

adding to Snowolfe's comment:
You must Install the exchange server with EXACTELY the same organization name, too. It's probably as important as installing exchange in the same directory as the crashed system

Good luck.

yes - very true - because if you had adjusted the location of the files, and didn't on the new server - they would not restore correctly

toloui - seeing as that has already been proposed - it's not exactly polite to be posting that as an answer
