Consider a practical situation wherein when you try to run an online backup of database after corruption, the operation is not completed and the following error message is displayed:

"Database page read failed verification because of a -1018 error" (page checksum mismatch)

Once the above-mentioned error message appears, you cannot access your valuable data and face the following problems:

  • You cannot send and receive email messages and other data items
  • You are unable to start the MS Outlook
  • Online backups fail to complete with a -1018 checksum error
  • Online defragmentation surfaces a -1018 checksum mismatch error

The reasons behind the above-mentioned error are the faulty hardware parts, firmware and device drivers of hard disk subsystem.

The aforementioned error message indicates checksum mismatch and the specific referenced database page within the Exchange store is corrupt.

In order to resolve the above-mentioned error message, follow the below-mentioned methods in the given order:

Test the system for hardware related issues: First of all, check the system for any hardware related issues. In order to recover hardware corruption problems, check the error logs and run the hardware diagnostics to see if the issue has occurred due to any hardware malfunctioning. To know the exact reason for the error, you can also swap the hardware components. However, before doing so you must take a proper backup of your valuable data.

Upgrade the firmware drivers if needed: If need arises, you must update the firmware drivers.

Restore from backup: If the EDB corruption is not caused due to hardware corruption problems, then you must check the availability of a proper, valid backup. If the last, valid, updated backup is available then you must restore your valuable data from the last, valid backup.

Perform EDB recovery using inbuilt eseutil /p utility: If you are unable to perform EDB recovery using the above-mentioned methods, use eseutil /p utility to repair the EDB database.

Use third-party EDB recovery tool: if following the aforementioned methods, you are unable to resolve the error and the erroneous condition still persists, use a professional, efficient, and result-oriented third party EDB recovery tool to perform EDB recovery.
