Get rid of Operation terminated with error -1605 message appeared while using Eseutil/p command

To resolve up the corruption issues existing in Exchanger server database, Eseutil/p is a command line inbuilt repair utility which is responsible to repair the corrupt Exchange server databases both at table as well as page level. But there are certain situations where this command line repair tool is unable to repair the damaged database that can lead to occurrence of error messages like Operation terminated with error -1605 etc and hence the best is to opt for edb repair tool.

Assume a situation where you are trying to repair the damaged Exchange server database using Eseutil/p command, but you receive the following error message on the screen:

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


The main reason behind occurrence of 1605 error is severe corruption issues which are beyond the capability of Eseutil/p command. It may build the B-trees incorrectly which in turn have an effect on the complete metadata structure of the database. This is the reason why you get the exchange error -1605(JET errKeyDuplicate).


In order to fix Operation terminated with error -1605 message, first of all you must get the latest service pack of MS Exchange Server 5.5 and then try to precede the repair process using the Eseutil/p repair utility, but even if the problem do not resolve, then the best possible option is to go for exchange server repair tool which meets up all your needs regarding exchanger server database corruption issues and thus repairs the corrupt database regardless of the reasons without wasting much of your time and effort.
