Description of 4 Steps to Fix ‘ Lotus Notes Public Key Does Not Match ’ Issue

In the version 7, documents of the server should be configured for logging this event. You can do this configuration procedure in the security tab. Well, whenever the mismatch problem occurs following log message appears :
These log statements help in determining the users who are facing this problem while working with the Lotus Notes email client.
Step 2: Create a Database to Hold All of the Errors
Putting off all the errors is not all required to troubleshoot the problem. You can take help of ‘log analysis’ feature for identifying all occurrences simultaneously. This feature is going to be helpful when you are having three or four servers on your premises. However, if there are 20 or more servers then, it will be painful to pull these log incidents out of the logs and result in mind-numbing experience. Administrators of the Domino server are quite busy in handling other business activities related to the server log in the large domain.
So, instead of opting for log analysis feature, pick any one of the servers (in which you think the error is taking place) and create a database via Monitoring results template. Give a title to the database and a name to the file, which shows that what it comprises.
Step 3: Capture the Logged Event and Place it in the Created Database
Open the database created in the Step (2) to fix Lotus Notes public key mismatch problem. You need to open this database in the Monitoring configuration of anyone IBM Domino server, available in your domain. After this, create an Event Handler.
During the discovery process, choose ‘All servers’ option and then select ‘Any event that matches the criteria’ option. This event is chosen because you are unknown from the particular event, which is causing the problem.
“Event must have this text in the message” is mandatory to be enabled in R5/6 configuration. This is required for holding a portion of the following error statement:
The following screenshot denotes the Event tab provided in the event handler screen for R5/6 :
You can refer the following statement if you are working with ND7 :
After completing with all the above instructions, configure Action to be “Log to a database”. Enter the database filename, which you have created and also name the server that involves it.
By default, this Event Handler is enabled for the Lotus Notes users. Now, you have to sit ideal for a while and let the database begin collecting the errors. In the end, you will come to know that which part of the database is having the public key mismatch.
