How to use ESEUTIL to repair/recover Exchange Databses?
Health of a databse: Run Eseutil /mh “Path of the database” and check the state of the database.
1. State= Clean Shutdown
Move log files from the Transaction logs folder location and mount the databse
2. State= Dirty Shutdown
Ensure that the log files required is in a Clean state by performing Eseutil /ml “Path of the log fileslog prefix” command
If the health status os ‘OK’ perform the Soft recovery with the command Eseutil /r <Log Prefix> /l “Path of the log files” /d “Path of the database”
Mount the database after completing the operation
Sometimes the ‘/i’ switch is also used when the operation has failed to complete
Hard Recovery
In the situation where log files are missing, restore from a successful back up or perform Hard repair
Once the restoration completes, a file named restore.env along with the logs that were backed up without being committed to the database will be created in C:Temp
Perform Hard Recovery by the command Eseutil /cc “Path of the restore.env containing folder”
restore.env file will be deleted after the completion of hard recovery
If we misses the sequence of logs, the recovery will fail and should use the command eseutil /cc “Path of the restore.env folder” /t to recover the databse
Hard Repair
Use eseutil /p “path of edb file”
Offline Defragmenation
Once Eseutil /p finishes we will need to defrag the databases. You must have available hard disk space equal to 110 percent of the size of the database that you want to defragment.

Florin Copil’s comment:
1. Do not forget to check the latest committed log against the db with Eseutil /mk “path to the checkpoint file”
2. You can move the logs which are already committed BUT you need to order them by date otherwise you might have some problems afterward with the backup.
That’s a cunnnig answer to a challenging question
My exchange dtabaase became inaccessible after a power failure, and I had the same error message popping up again and again. I tried to fix it using inbuilt tools, but that didn’t help. I got to know about this tool from a friend and thought of giving it a shot. The demo version showed me all of my data and after purchasing the software, I recovered everything. This is really a great tool and the interface is pretty easy to understand.
Hy ManU, Thanks for the detailed steps. With the help of your piece of writing and research i completed mine – http://exchange.stellarservertools.com/blog/resolve-unable-to-mount-exchange-database
