C:\Program Files\Microsoft\Exchange Server\V15\Bin\

cd C:\Program Files\Microsoft\Exchange Server\V15\Bin

The next thing that the user requires to do is to check whether the space required for the process is available or not. You may be required to open the 1221 event in order to check the whitespace in the Exchange database if the size of the database is somewhere around 10 GB. So, after that, you need to subtract the whitespace space from the total database size. The remaining size is the space that the user needs to allocate for EseUtil to repair EDB files.

Step: 3 Check the State of the Database

Users can use the /MH switch to identify the state of the Exchange database. If you find the state is clean shutdown then there are no issues and the Exchange database can easily mounted. Moreover, if the state of the database is shown as dirty shutdown then in that case the situation indicates a corrupted database. It may happen because of the unavailable or deleted log files.

Step: 4 Check Log Files

After checking the database state you need to check whether the logs are in a healthy state or if there is some problem with them.

Users can use the log path which you can get from log with the ML prefix with EseUtil utility.

If in case if the log status shows that they are healthy you will see a message that is No damaged log files were found.

Step: 5 Performing Soft Recovery

Once you get confirmation that your logs are in a healthy state you can easily initiate the soft recovery by making use of the EseUtil/r parameter.

You can utilize the EseUtil/mh command after the process completion in order to check the state of the database. Use Mount database cmdlet to mount the database.

Step: 6 Initiating Hard Recovery

We suggest users to only perform the hard-recovery only when the soft recovery of the database has completed failed. Hence, the hard recovery can be executed with the /p parameter.

To execute the process and to get maximum results enough storage is required. After initiating the process you will be warmed with a message which reminds you about the damage. To move ahead you must accept the message stating the warning.
