Eseutil/p is an inbuilt repair utility of MS Exchange Server that repairs corrupted Exchange Server databases at both table and page level. While the repair utility proves successful in repairing most of the corrupted databases, there are certain situations wherein the command fails to repair a corrupt database. In such situations, it displays an error message. This happens when the database is severely damaged. Since the database cannot be repaired, it remains corrupt, and the data saved in it remains inaccessible. To access database in such situations, a user needs to restore database from a previous online backup. However, in the absence of an updated backup, a user needs to repair the database using a Exchange Repair application.

For detailed explanation of the above problem, consider a practical case wherein your Exchange Server database gets corrupted. And, when you try to repair the database using Eseutil/p utility, you encounter:

“Operation terminated with error -1605 (JET_errKeyDuplicate, Illegal duplicate key) after xxx.xxx seconds.”

Data saved in the database becomes inaccessible after the above error message appears. Additionally, the same error message repeatedly occurs when you try to repair your database.

Cause:

The fundamental reason for the occurrence of the above error message is that the repair utility might rebuild B-trees incorrectly. This will change the complete metadata structure of the database, leaving it in a permanently non-repairable state.

Resolution:

To resolve the above error message and to access the records saved in the database, a user needs to obtain the latest service pack of MS Exchange Server 5.5 and perform repair. However, if the repair utility is unable to repair the database even after installing the service pack, then you need to opt for an advanced commercial Exchange Server Repair application.
