Repair database files in this store are damaged – Error

An error message when opening a Microsoft Exchange Server database mainly occurs when the database becomes corrupted or damaged. In most situations, database corruption occurs due to improper, unexpected, or dirty shutdown. Corruption in the Exchange database can be remedied by using a repair utility known as ‘ESEUTIL / P’. This utility checks the logical and physical integrity of the database and makes repairs to the highest possible level. However, there are certain situations in which the database remains damaged when this utility cannot be repaired. In such situations, the user must restore the Exchange database from an adequate and complete backup. But if no backup is available, then you need to restore Exchange database (.edb file) using effective third party Exchange Server Repair software.

To illustrate the above case, consider a practical scenario where you will encounter the below error message that appears after corruption in the Exchange 2003 database:

“The database files in this store are corrupt ID number: c104173b ESM”

After the above error message is displayed, all data (emails, contacts, notes and more) will become inaccessible. When viewing the event log, you will come across the following information:

“EventID 465

To overcome the MS Exchange database corruption error message above, please follow the steps below:

1. Use the built-in repair tool ‘eseutil / p’ to repair the database.

2. If the job fails and you have not backed up, use a commercial Exchange Server Repair application. Such third-party tools perform absolute Exchange repair after almost all logical crashes.
