Go to Servers > Certificates and select the server on which you have already installed the certificate.
2. Select “Export Exchange Certificate”
Click on the More icon “…” & select the option “Export Exchange Certificate”.
3. Choose a destination and a password
Enter the exact path & name of the folder you want to export the SSL/TLS Certificate to. You’ll be prompted to create a password for your certificate. Make sure to keep .PFX as the file extension.
