Overview

If you have renewed your expired SSL certificate with your certificate provider and received a .crt file, you must import the renewed certificate into Kerio Connect.

This article provides the steps to import the renewed certificate by using the administration console or importing the certificate manually.

 

Note: When renewing an SSL certificate from the same server, Kerio Connect uses the same private key that was initially used for generating the first certificate.

When importing an SSL certificate from another server, the SSL certificate uses a different private key, that is proprietary from the source server. If the original private key is not copied from the source server, the actual certificate will not be viewable from the Webadmin GUI (Graphical User Interface).

Importing SSL Certificates Manually

2. Go to the SSL certificate folder for the MailServer.
   
   The default locations of the SSL certificate folder for each operating system are listed below.
   • Windows: C:\Program Files\Kerio\Mailserver\sslcert
   • Linux (root): /opt/kerio/mailserver/sslcert

3. In the SSL certificate folder, make a backup of the .crt file that has the same name as your active certificate.
4. Rename the new certificate (.crt file) to match the name of the active certificate. Copy the new certificate to the SSL certificate folder (replacing the previous active certificate).
5. Start Kerio Connect.
6. If there are any issues, stop Kerio Connect and perform the following steps:
