Error in MS Exchange Server JET_errKeyDuplicate Illegal duplicate key

Eseuti/ P is the inbuilt utility which is used to solve some of the database corruption problems. The Exchange recovery is made possible through the database checking and repairing critical structures inside the database (such as system tables, attachment tables, and so on) and checking for damaged pages in the databases. But this comes with the disadvantage that as soon this finds a damaged page, it deletes it and thus leading to data loss.

Another disadvantage is that this cant repair most of the jet errors. The lack of the power of the utility not to address some of the critical Exchange Server corruption problems lead to the database corruption problems unresolved. One such error message is:

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

At this point of time, the Eseutil /P may exit prematurely while processing the file.

Reason
The reason behind this failure of the utility to have Exchange Server recovery is the inability to re-build the b-trees incorrectly. 

Solution
The Exchange recovery has been declared as impossible by the inbuilt utility of Exchange Server in this case. So this requires that the specific case should be handed over to the third party application software, particularly named as Exchange Server recovery software.

If you have the back up then this will prove to be more beneficial comparatively. But if this is not in the complete form then the use of third party applications is required.

These EDB recovery software make the part of the user quite easy and the repair process quite effective. The software yields the corrupted database in the complete and unaltered state. The reason for the same being the use of the powerful algorithms and the read-only nature of these software.

Data is the significant term for any organization and risking this at the cost of the quality of the EDB recovery software is not accepted. So make the use of the software which is quite effective and popular for the same.

Stellar Phoenix Mailbox Exchange Recovery has marked the tremendous performance in this era. This Exchange Server recovery software uses the most powerful algorithms to scan the corrupted database.

After EDB recovery, the recovered data will be saved in the PST file format and thus can directly be used with MS Outlook. The software can be used with Microsoft Exchange Server 5.5, 2000 and 2003.
