How to Solve Page Checksum Mismatch Error in MS Exchange Server ?

MS Exchange Database files get corrupted or damaged due to many reasons such as abnormal shutdown of Exchange Server, Virus attack, hardware failure and more. When this type of situation occur , the database becomes totally inaccessible and unusable. In case of edb file corruption , you may encounter critical user's data loss situations and at this point, EDB Recovery is the best way to get your data back.

When EDB file gets damaged or corrupted, you would not be able to access your data such as email messages, contacts, notes, tasks, calender entries etc with MS Outlook. This behaviour occurs because MS Outlook will not be able to access your data from the corrupted mailboxes.

Consider a practicle example, when you try to run an online backup of database after corruption, the operation can not be completed and you come across the following error message:

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

You can not access your valuable data from the database after above error and users might face the following problems:
  • Cannot send or receive e-mail messages and other items.
  • Unable to start MS Outlook.
  • Online backups fail to complete with a -1018 checksum error.
  • Online defragmentation surfaces a -1018 checksum mismatch error.
To gain access of your data in MS Outlook, you need to identify the root of this issue and perform EDB to PST conversion.


The root cause of this error is that faulty hardware parts, firmware and device drivers of hard disk subsystem. The error -1018 indicates checksum mismatch and the specific referenced database page within the Exchange store is corrupt.


Try the following steps to resolve the issue:
  • Test the system for related hardware issues and replace it
  • Upgrade the firmware drivers if needed
  • Use the last available online backup to restore the exchange database.
  • Perform hard recovery using inbuilt eseutil /p utility or use a third-party EDB PST Converter such as Stellar Phoenix Mailbox Exchange Recovery.

The EDB to PST Converter will help you to get your precious data back by performing in depth scanning and repairing of entire EDB (Exchange database file). To Convert EDB to PST, the tool has interactive graphical user interface and there is no need to be technically sound to use it.

Stellar Phoenix Exchange Server Recovery is the most powerful and multi-featured edb to pst conversion tool that ensure complete EDB Recovery in all instances of .edb file corruption. The EDB to PST Converter works well with MS Exchange Server 5.5, 2000, 2003, 2007 and 2010. The tool is compatible with Windows 2000, Windows XP, Windows 2003, Vista and Windows 7.

The free demo version is also available to evaluate the Convert EDB to PST Software that allows users to repair corrupt edb file and extract the user mailboxes. However, it restricts the user from saving the extracted data and required full version to save the same.
