How to recover emails from a dismounted Exchange database?

Steps to recover emails from a dismounted Exchange EDB

Eseutil is a command line tool and a Microsoft Exchange server utility that can repair an Exchange database file. It is strongly advised that you make a complete backup copy of the Exchange database file before proceeding with the steps.

• Step 1: Launch Eseutil from the Exchange server bin directory

  Navigate to the directory where the Exchange server is installed and locate the eseutil tool in the bin directory. You can also perform a Windows search to locate the executable.

• Step 2: Check the status of the Exchange database from eseutil

  Execute the command eseutil/mh on your database to check its status. This command checks for any errors and displays if it is in Clean or Dirty Shutdown.

• Step 3: Remount the database if there are no errors

  If the status from the proceeding step is Clean Shutdown, it means that the transaction logs have been committed to the database. You can remount the database with the cmdlet Mount-Database –Identity and restore your emails to the Exchange server.

• Step 4: Perform a soft and hard recovery if the database fails to mount

  However, if the status shows Dirty Shutdown, you cannot mount the database without performing a recovery. To perform the soft recovery, copy paste the missing Exchange transaction log files into the database folder and run the cmdlet eseutil/r to reply the logs to the EDB.

  If the log files are missing, the only option is to perform a hard recovery with the cmdlet eseutil/p.Remember that the hard recovery operation purges any unrecoverable data and results in a data loss.

• Step 5: Defragment the Exchange database after the recovery operation

  Run the cmdlet eseutil/d to defragment the Exchange database. Perform an integrity check with the IsInteg tool.

• Step 6: Mount the EDB to the Exchange server

  Finally mount the database to the Exchange server with the cmdlet Mount-Database –Identity. If the database still does not mount, perform a Dial tone recovery operation.

The above method has the limitation that if your database is corrupted and is in the Dirty Shutdown state, running eseutil/p for hard recovery will result in permanent data loss. Furthermore, downtime is unavoidable during this operation, and you will be unable to remount the database until it has been recovered. In such a case, the only option is to use EdbMails, a trusted and safe solution to completely recover and restore the database.

  Connecting to the target Exchanger server enables you to map the folders and mailboxes from the source to the target. Verify the mapping and start the migration operation.
