Exchange Database Corruption – Causes
Hardware Issues: Hardware is a major reason for Exchange issues. The bad sections in the hard drive where the Exchange data is stored cause database inaccessibility. Such as Motherboard failure, overheating, and other problems can damage the hard drives; failure of drives holding the database or log files which can cause Exchange issues.
Accidental Shutdown: The accidental and sudden shutdowns force Exchange information stores to close down without writing the transaction log files property in the database files. Such shutdown can occur due to sudden power failure or user errors.
Server Failure: Therefore, the Exchange Server can fail due to various reasons such as OS stop error, processor chip/motherboard/communication issues, etc. It may experience downtime as a result of network issues, system overload, and hardware issues too.
Database Grown beyond the Storage Limit: Excessive growth of the Exchange database can cause issues.

It may get corrupted and lost forever too.
Repair Corrupt Exchange Database With Eseutil Tool Manually
Follow the steps to use the EseUtil software to repair Exchange databases when backups are not available or do not work. There are six steps to complete the process manually:-
Step 1: Locate the Corrupt Database (EDB) File and Logs
When Exchange server is set up, the Exchange database(EDB) file is created at the default location:
C:\Program Files\Microsoft\Exchange Server\V15\Mailbox\
Therefore, the administrators can store the database file in a different folder or different drive volume for the performance and other reasons. Users need to first locate the damaged EDB file to repair it. And, you also need to locate the transaction logs (.log) and the checkpoint file (.chk).
Step 2: Check the Database Status
Check the current database state using the EseUtil command, which is follows below:-
Firstly, Press “Windows + R”, type \EXCHSRVR\BIN, and click on the ‘OK’ or press the ‘Enter’ key.
Now, click on the Address Bar and copy the EseUtil.exe location path
The Open Exchange management shell (EMS) and then navigate to the Eseutil.exe location using the ‘cd’ command
Then, execute the following command in the powershell window:-
Eseutil.exe /mh
Eseutil.exe /mh C:\mbx01\mbx01.edb
This command output will display the database header information. To check the ‘state.’ If it is displayed as ‘dirty shutdown,’ the database is inconsistent or corrupt and requires recovery. If the state is ‘clean shutdown,’ the database is in a healthy state and mounted to the server with no issues.
Step 3: Back Up the Database Files
So, after verifying and locating the Exchange server database file, back up the EDB, transaction logs and checkpoint files before using the EseUtil software. And, you can backup the database files into another folder, volume or external media.
Step 4: Execute Soft Recovery using EseUtil
Whenever EseUtil is executed with the \r parameter, it referred to as ‘soft recovery.’ When executed on the corrupt database, the Eseutil tries to commit the transaction logs and restore the database for a healthy state without losing any data. It works when there is a minor database corruption.
So, to perform software recovery, execute the following commands:-
EseUtil /r
EseUtil /r C:\mbx01\mbx01.edb
Step 5: Verify the Database Status
Now, to check if soft recovery was successful and the database is now in a ‘clean shutdown’ state’ execute the following command:
EseUtil /mh C:\mbx01\mbx01.edb
After checking the state. If it still appears as ‘dirty shutdown,’ you need to perform a ‘hard recovery’ to recover the Exchange database.
It may take a while as it depends on the server’s performance and storage, apart from this the size of the database.
Step 6: Perform Hard Recovery using EseUtil
It should used only when soft recovery has failed and restoring from backup is not possible. Hard recovery is executed with the \p parameter.
Caution:
The EseUtil/p command purges the irrecoverable data and mailboxes,, i.e., removes anything it deems corrupted or unreadable from its database during recovery. Then, hard recovery can lead to the significant data loss you might discover later.
Whenever you execute the EseUtil/p command, a data loss warning is displayed, which you need to accept to proceed further.
We highly recommend backing up the database before running the EseUtil/p command on the database.
IMPORTANT NOTE: Hard Recovery does not guarantee database recovery (clean shutdown), and you may still fail to mount the database. When the process is successful, we highly recommend creating a new Exchange server mailbox database and moving the mailboxes into it. As a process is done, decommission the old recovered database.
