Check Exchange database health
The health of your Exchange database is crucial for maintaining seamless email communication and the stability of your IT environment. As the central repository for user mailboxes and emails, the Exchange database (EDB) supports day-to-day operations. However, over time, issues such as corruption or database dismounts can compromise accessibility, leading to downtime and potential data loss. Regular checks and maintenance are essential to ensure your database remains in optimal condition and minimize the risk of disruptions.
When faced with database corruption or mounting issues, EdbMails EDB to PST converter provides a reliable solution. This tool allows you to recover mailbox data directly from an offline EDB file, converting it to PST format and ensuring you can access important emails, contacts, and calendar items.

How to check the health of the Exchange database?
The following methods will guide you in identifying issues with Exchange server services and help you repair the database if corruption occurs, applicable to Exchange Server 2019, 2016, 2013, and 2010.
Method 1: Restart the Exchange server services
If Exchange server services are not running, you may encounter errors such as Database status is unknown, preventing users from connecting to their mailboxes. To resolve this, simply check whether all Exchange server services are running. Restarting any necessary services should restore normal operation and allow users to access their mailboxes again.
- Press 'Window Key + R' and type 'services.msc'
- Find the service named Microsoft Exchange Information Store and Microsoft Exchange Mailbox Replication. Right click on the item and select 'Start'. If the service has been disabled or stopped, click 'Restart'
Method 2: Check Exchange database health with PowerShell
For the second method, you must open the Exchange Management Shell (EMS) as an administrator and run the following cmdlets.
- To get the information about the mailboxes in the Exchange server, use the Get-MailboxStatistics cmdlet. The following example returns the mailbox statistics for all the mailboxes on MailboxServer02.
Get-MailboxStatistics -Server MailboxServer02
- To get information about a single user mailbox, run the following cmdlet
Get-MailboxStatistics -Identity JohnDoe
- The Test-ServiceHealth cmdlet checks if all the Exchange server services have started running which is analogous to manually starting the services described in method 1.
Test-ServiceHealth
- Run the Test-Mailflow cmdlet to check whether you can send and receive emails from the mailboxes. For example, the following cmdlet tests the mail flow from mailbox 1 to mailbox 2 on the Exchange server.
Test-Mailflow MBX1 -TargetMailboxServer MBX2
- The Test-MAPIConnectivity checks for the server functionality
Test-MAPIConnectivity
- The Get-MailboxDatabase cmdlet returns one or more database objects from a server. The following example returns the information for the mailbox database MBX01.
Get-MailboxDatabase -Identity MBX01 -Status | Format-List
- To get the information about the mailboxes in the Exchange server, use the Get-MailboxStatistics cmdlet. The following example returns the mailbox statistics for all the mailboxes on MailboxServer02.
Method 3: Check the database status with Eseutil
Eseutil is a Microsoft-built command-line utility that helps you check the status of your Exchange database and perform repair operations when issues are detected. If the database is in a Dirty Shutdown state, a soft repair is required to return it to a Clean Shutdown state before it can be mounted to the Exchange server. Let's explore the cmdlets you can use with Eseutil to repair the database and restore normal operation.
- Step 1: Launch eseutil.exe on your Windows computer
The Eseutil is located in the bin directory where you have installed the Exchange server.
- Step 2: Run the following cmdlet to check the database status
eseutil/mh
- Step 3: Check the database status for Clean or Dirty Shutdown
If the database is in the Clean Shutdown state, you can remount it easily. If it is in the Dirty Shutdown state, it means that the log files are missing and you most likely have to perform the Soft and Hard Recovery operations.
- Step 4: Perform the repair operation on the database with eseutil
To perform the soft recovery, run the cmdlet eseutil/r
In the following cmdlet, r stands for recovery, l stands for the location of the transaction log files and d stands for the database path. E01 is the missing log file you need to copy into the log file folder for the soft recovery operation.
eseutil /r E01 /l C:\Exchange\EDB /d C:\Exchange\EDB\DB02
Note that after you perform soft recovery, you can check the database status with eseutil/mh command. If the database fails to mount to the server, you need to perform a hard recovery operation with the cmdlet eseutil/p

One limitation of using Eseutil for hard recovery is that it may fail to repair a severely corrupted database and requires familiarity with PowerShell cmdlets. Additionally, the hard recovery operation purges all data that cannot be recovered, resulting in permanent data loss.
Along with Eseutil, you can use the New-MailboxRepairRequest cmdlet to detect and resolve mailbox corruption issues. This method provides a more targeted approach to fixing problems without risking widespread data loss. For comprehensive database management, also explore how to check and monitor mailboxes in Exchange server 2019 and 2016, as well as the best practices for managing user accounts.
