If you run thru the prior restore step (Exchange Restore) and cannot mount the recovery database you can try the following commands on your Exchange server
Step 1
Verify that the database is in a clean shutdown state. To do this run ESEUTIL /MH “.edb file location”
In our case the command would be eseutil /mh r:\rdb\rdb1.edb
Look at the state value to see the status. For this example our DB showed dirty shutdown
Step 2
If the database is in a dirty shutdown state you can perform a soft recovery by running the following command:
eseutil /r Enn /L “Path of the log files” /D “Path of the database path”
In our case it would be:
eseutil /r Enn /L r:\rdb /D r:\rdb\rdb1.edb
**The “Enn” listed in the above command is the prefix of the log files**

Step 3
After the soft recovery is completed, run eseutil /mh again to check the status of the database.
Step 4
The database should be in a clean shutdown state now. If so you will be able to mount the recovery database.
