This article provides steps on how to resolve this error message.

Prerequisites

• Admin access to Kerio Connect server.
• The latest version of Kerio Connect is installed.
• Ensure that the Kerio folder (in this case D:\Kerio\MailServer) is excluded from any Antivirus software or firewall installed on the server.

Solution

1. Stop Kerio Connect.

2. Navigate to the folder reported in the logs (i.e., D:\Kerio\MailServer/plugins/).

3. Download the attached zip file containing the kavmodule.dll file.

4. Extract the content of the zip file to the directory in step 2.

   Note: The DLL file attached is from a server running version 9.2.10. Please ensure that the affected server is running the same version to avoid any issues after copying the DLL file.
