Kernel for Exchange Server Software Review


EDB files hold the information of Exchange Server that stores the complete data of MS Outlook mailboxes. Each time when the Outlook performs send or receive process, the emails and other items of user mailboxes get automatically stored in Exchange database (EDB) files. However there is a drawback associated with the Exchange database file as it may become susceptible to corruption, when go through any kind of unfavorable conditions like Exchange Server failure, accidental system shutdown, virus intrusions, JET engine errors, hard disk failure etc.

Symptoms of Exchange Database Files corruption

  • Unable to start/stop Exchange Server Information Store
  • Abnormal termination of Information Store
  • MS Outlook email client is unsuccessful to send emails
  • Even after restarting Information Store, user is unable to send/receive emails
  • The Information Store fails at responding and CPU consumes 100% usage.

No matter what reason or source is responsible for the cause of EDB file inaccessibility, but once it is corrupted then using a third-party EDB file recovery software is the only feasible option to deal with it and fix the error.

‘Ins and Outs’ of Software with Pictorial Help

How the software works? What convenience does the tool provide to recover the corrupt EDB & STM files? Find all these answers here in this detailed product review section to get a clear understanding of the tool’s Interface and its behavior.

EDB File Selection

When you will launch Kernel for Exchange server software, it will land on the main screen. Wherein, the user is requested to select the corrupt Exchange database file for recovery. For user convenience, the tool provides two options, i.e. ‘Browse’ and ‘Search’ – to select EDB file location from the selected volume of the drive.

  • Browse EDB/STM File: This option is useful in case you are aware of the exact location of the corrupt EDB and STM files that are needed to be recovered.
  • Search EDB File – Make use of this option to quickly search EDB file in case you are not aware of the exact path of the damaged EDB file.

EDB File Recovery

Upon selecting the respective EDB files, it’s the time to perform rigorous scanning and then recovery. For this, the tool provides two robust recovery modes, i.e. Standard Scan and Advanced Scan.

  • Standard Scan: Use this mode of recovery to handle mild corruption issues in EDB files. However, this recovery mode repairs the user mailbox information at the fastest pace due to low intensity of corruption in EDB and STM files.
  • Advanced Scan: Select this recovery mode to repair severely corrupt, inaccessible EDB files. You can even use this mode to restore the EDB files, which are unable to be repaired using Standard Scan.


The great aspect about the software is that it also allows user to perform the EDB file recovery by using additional criteria such as selecting ‘From’ field in the message table and using Disk Space. Using the two modes, you can repair all types of corruption errors (in just a few clicks), such as displayed below:

  • Exchange Server goes down 
  • “Operation terminated with error -1601 (JET_errRecordNotFound, the key was not found).”
  • “The information store terminated abnormally”
  • “JET_errRecordNotFound, the key was not found”, “Jet_errRecordDeleted”
  • Exchange Server Error Code 528 
  • “The System Cannot Find the Path Specified”
  • “Error Opening Message Store”
  • JET_errBadDbSignature -531 
  • JET_errDatabaseStreamingFileMismatch -540 
  • JET_errDatabaseDirtyShutdown -550 
  • JET_errConsitentTimeMismatch -551 
  • JET_errInvalidDatabaseId -1010 
  • JET_errInvalidDatabase -1028
