The requested operation failed” Error

Hi
I have installed (KOC) which is an acronym for Kerio Connect Offline Edition and switched to a build beta which was successful, but later when i restarted the outlook and while pressing double click I am getting the error message appeared as shown in below image.
Please can anyone provide me with the exact solution to this problem?
