A key identifier enables a user to select a key design functionally compatible with a known key in the database to access your important data from the database. Exchange Server allows you to have a duplicate key in your database to make replica of the database as a backup.
A duplicate key (identifier) can also be created to access data by general means. In case of original key corruption, the dataset access can be continued by using the duplicate key. But sometimes, you may find that duplicate key is also causing problem or got corrupted. In such situations, you may receive the following error message:
"Operation terminated with error -1605 (JET_errKeyDuplicate, Illegal duplicate key) after *.edb seconds." At this point of time, the Eseutil /P might exit prematurely while processing the file. The reason behind this failure of the utility to have Exchange Server recovery is the incapability to re-build the b-trees perfectly. "
Note: Eseutil/P is the inbuilt Exchange server utility which is used to fix some of the database corruption problems. The Exchange recovery is made possible through the database checking and repairing the critical structures inside the database (like attachment tables, system tables and so on) and checking for corrupted pages into the database.
Though, this utility is useful in some of the database corruption situations, but it comes with the disadvantage that as soon as it finds any corrupted page, it removes it and thus resulting in the data loss.
Another downfall of this utility is that it can't repair most of the jet errors. The lack of the influence of the tool not to identify some critical Exchange Server damage problems causes the inaccessible state of the database and ultimately the data loss.
In such grave situations, you need for a powerful tool that can systematically scan the database and can recover the database in the original state. Such tools are known as Exchange Server recovery software.
