You can use EdbMails to recover mailboxes from Exchange database issues such as Inactive, Down, Inconsistent, Dismounted Database, Dirty shutdown or Unavailable Exchange Server. The application does not require Exchange server services or Active directory to recover an offline and corrupted EDB.
Recovering a corrupt Exchange database is straightforward with EdbMails. Simply locate and select an offline EDB file and allow the application to recover your mail data. EdbMails is intended to read large Exchange EDB files and recover data in granular fashion. It performs a full scan of the file, removing any index corruption and restores the data in its original structure and form.
Exchange server is a Microsoft email and calendaring service that stores a large number of emails, folders, attachments, and contacts. An Exchange server in a very large enterprise may have TBs of data, and it is important to keep the Exchange server operational to ensure continuous workflow and communication. Exchange server runs on the Windows Server operating system, and it is essential to understand where the server is installed and the components that make it up. When you install the Exchange server in its default location C:\Program Files\Microsoft\Exchange, it creates a database file called database.edb as well as additional log files.
When Exchange log files are lost before they are committed to the database, the data in the logs is no longer written to the EDB, causing the database to become inconsistent. The Exchange server develops Jet Errors such as JET-Error -533 (0xffffdeb), JET-Error -515 (0xffffdfd), JET-Error -501 (0xffffe0b), and JET-Error -514 (0xffffdfe), and the database fails to mount as a result. You cannot access your mailbox in such a situation you must perform a complete database recovery to recover the Exchange server from Jet Engine Errors.
There are two methods to recover an Exchange database without log files. In the first method, you can retrieve the most recent log files from a backup copy and so that the Exchange server can replay the log files and restore the database to a consistent state. If you do not have a prior backup of the Exchange server data, use the Eseutil utility to repair and remount the database, or use EdbMails Exchange recovery solution to thoroughly repair and convert the EDB file to PST.
To check the status of the database and perform the recovery, you must use the Eseutil tool, which is installed in the same location as your Exchange server. On most systems, this is located in the C\Program Files\Microsoft\Exchange server\bin folder. Eseutil is used for verifying, defragmenting, and recovering the corrupted Exchange database files. It is also important to take a complete backup of the Exchange database file, as well as any log files, and unmount the database before you attempt the recovery operation.
If the database displays Dirty Shutdown, you must perform a soft recovery first. Copy paste the missing transaction log files to the folder in the Exchange server directory and run the cmdlet eseutil/r to replay them to the database.
Run the cmdlet eseutil/d to defragment the database and run an integrity check with the IsInteg tool to scan for any errors. If no errors are found, run the cmdlet Mount-Database -Identity name.edb to mount the EDB to the Exchange server.
EdbMails is Microsoft-partnered Exchange recovery software that can repair and convert EDB to PST from Exchange 2019, 2016, 2013, 2010, 2007 and 2003. It can fix Exchange server problems, database corruption, and mounting issues by recovering offline, disconnected EDB files without connecting to an Exchange server. You can export mailboxes from EDB to Outlook PST format or directly migrate EDB to Office 365 or to another Exchange server.
It can be time-consuming to recover an Exchange database, especially if the log files are missing. These files can go missing for a variety of reasons, and recovering the exact copy and replaying them is a significant challenge. One option is to recover the log files from a backup, but this does not work if the backup is a little out of date. Microsoft utility eseutil provides a repair option, but if the transaction log files cannot be found, the only option is to perform a hard repair, which can purge and result in data loss. The best solution is to use EdbMails EDB repair software, which can perfectly recover the database files and restore your Exchange server to operational status without the need for log files or data loss. It can convert EDB to PST or directly migrate to a healthy Exchange server in a few steps.
Using EseUtil, administrators can repair corrupt Exchange databases and restore the mailboxes in events such as uncommitted logs, missing or deleted transaction logs, server crashes, abrupt shutdown, malware, etc. EseUtil helps in situations when Exchange backups are outdated, damaged or not available.
After locating and verifying the Exchange server database file, back up the EDB, transaction logs and checkpoint files before using the EseUtil tool. You can back up the database files in another folder, volume or external media.
Eseutil/p command purges the irrecoverable data and mailboxes, i.e., removes anything it deems corrupted or unreadable from the database during recovery. Thus, Hard Recovery can lead to significant data loss you might discover later.
Hard Recovery does not guarantee database recovery (clean shutdown), and you may still fail to mount the database. If the process is successful, we highly recommended creating a new Exchange server mailbox database and move the mailboxes into it. Once this is done, decommission the old recovered database.
Dirty Shutdown is a database state that occurs due to missing, deleted, or corrupt transaction log files. When a database is in Dirty Shutdown state, it prevents the Microsoft Exchange database from mounting, causing disruption in email services. However, this complex problem can be quickly resolved by repairing the EDB file using this advanced Exchange recovery tool.
At times, the Exchange server database fails to mount and displays an error message, such as 'Failed Error: Couldn't mount the database that you specified.' The solution is to restore the Exchange database from an updated backup or apply an effective Exchange EDB repair technique, like Stellar Mailbox Exchange Server Recovery.
When Exchange server crashes, an administrator can use setup /m: RecoverServer switch command to rebuild a new Exchange server. However, database recovery is a more challenging task, based on the nature of the failure. Stellar Toolkit for Exchange helps you recover mailboxes from .edb file of crashed Exchange server, especially when ESEUtil fails, logs are missing or deleted, and backup is not available. See ESEUtil & Stellar Repair for Exchange Comparison.
The Exchange EDB recovery tool can process up to 4 mailboxes at a time during database repair. This parallel processing of mailboxes helps reduce the time required to repair and save mailboxes from a damaged or corrupt Exchange database to PST, Office 365, or Live Exchange server. The number of mailboxes that the software process at a time depends on the available RAM of your computer. You can stop mailbox processing by removing it from the queue. However, the software provides you with an option to resume recovery of the removed mailbox after processing and saving the remaining mailboxes. Learn More
