Like its previous versions, Exchange Server 2019 also makes email communication between businesses easier, quicker, and more efficient. It has introduced several features to ensure the security of email messages.
However, there is always the possibility of threats that make the databases corrupt, making them inaccessible. Several factors responsible for damaging the databases in the Exchange Server may include virus attack, database object errors, and sudden system shutdown or user error.
At times, application malfunctioning or improper modifications in the schema of the database could also be the reason behind this corruption issue.
The need is hence to repair the database in Exchange Server 2019 so that business communications within organizations continue uninterruptedly.
Detecting corruption in Exchange Server Database 2019
In the Exchange Server 2003, 2007, 2010, 2013, 2016, and 2019, you can follow the steps below to check for corruption in your Exchange database. Follow the below-mentioned steps to check the Exchange database for corruption.
- Open Eseutil.exe
- Find the database state ā Clear Shutdown or Dirty Shutdown by eseutil /mh command
Please note that a clean shutdown state will ensure an error-free database. Likewise, a dirty shutdown state will indicate an inconsistent and corrupt database, necessitating the recovery.
You can repair your corrupt database by running the EseUtil command or by using a third-party tool Exchange EDB recovery tool such as Stellar Repair for Exchange. Using the latter method is much better as it sets you free from the hassles of the cumbersome and time-consuming manual method. Letās check out both of these methods.
Repairing Exchange Server Database 2019 using EseUtil Command
Before proceeding with Exchange Database recovery by using the EseUtil command, make sure that you have the following:
- A recent backup of your Exchange database (EDB) file
- Administration permissions or access
- Free storage space, which should be around 1.2 times the size of the database
Here are the requisite steps:
Step 1: Find EseUtil.exe utility. It should be in the exchsrvrbin directory created at the time of Exchange installation on your server.
Step 3: Check the database state through the following command: eseutil /mh <database file name>
In case of a dirty shutdown, the database will face mounting issues making it corrupt or damaged. This may occur because of deleted, missing, or uncommitted log files
Step 4: A dirty shutdown will also show the required log file. Check the health status of the log file by using ML prefix with EseUtil in combination with the path of the log. You can copy the path from the reportās LogRequired section.
eseutil /ml “M:Log File Name logs”
e.g., eseutil /ml “M:mbx03 logs”
Step 5: In case of healthy logs, you will get the message āNo damaged log files were found.ā This will allow you to carry out soft recovery with the help of EseUtil /r parameter.
e.g. Eseutil /r e00 /l “M:mbx03logs” /d “M:mbx03database”
After running this command, recheck the state of the database through the Eseutil /mh command. Next, use the Mount-Database cmdlet to mount the database. This soft recovery will take considerable time to repair the database, depending on its size and the extent of damage done.
Step 6:Ā Despite the soft recovery, the database may still get a dirty shutdown state. In any such instance, hard recovery is the next resort. Performing hard recovery will result in permanent loss of the damaged data. Therefore, you should be careful before opting for it. A wise move would be to create a recent backup of the EDB file.
You can start hard recovery by running the eseutil /p command. You will receive a warning regarding the data loss. Accept the warning and continue repairing the Exchange database.
Demerits of using EseUtil
While EseUtil can help with Exchange Database recovery, it does come with certain limitations
- As already discussed, it may lead to even more loss of data subject to the level of database corruption and the recovery method used.
- The entire EseUtil process takes many hours to complete. During this time, you may not be able to use mailboxes or carry out email communication, hence leading to business losses.
Consider using Stellar Repair for Exchange to overcome these limitations.
