Restore information store after server crashed

We have a server that crashed, however, we only lost the OS partition (C: Drive)

When we installed Exchange we installed the info on the D: drive which is all in tact. We are currently in the process of reinstalling the OS and recreating AD.  Is it possible to mount the old store from the old files?  If so, how can it be done?

Hi,

You should be able to recover by re-installing Exchange using the disaster recovery switch. This article should you help. I am guessing you are using Exchange 2003.

you can mount the mailbox store into the recovery store and then move the data over to the new mailboxstore that will get made once it is installed.

I don't think you can just remount the old mailbox store or if it is a good idea because your remaking the whole server again so there may be a few different settings somewhere.

What about the AD? are you going to install the new AD or restore from backup ?

if it is new AD then disasterrecovery switch and RSG thing will not work.

if you creating new AD altogether

1 - Create AD

2 - install Exchange all overagain. ( Exchange saves info in AD and old is gone)
When you install new Exchange make sure you use old Exchange Organization name and Admin group name.
if you dont know the name run following command
find /i "ou=" "path to .edb file" you will get a result with org name and admin group name.

3 - Once exchange is build swap the new database with the old server's database and on the mailbox and public folder's properties just check "this database can be over written by backup"

You should be able to mount the database and you will see all the mailboxes in disconnected state ... using tolls like MBconn you can create a correspondant user in AD and connect those disconnected mailboxes with the user account.

See below article for using Mbconn
