Resolution

Connect to the server via SSH
Create the custom template folder:

# mkdir -p /usr/local/psa/admin/conf/templates/custom
Copy the Kolab custom template:

# cp -r /usr/local/psa/var/modules/kolab/webmail /usr/local/psa/admin/conf/templates/custom/
Set a proper name to the configuration file:

# mv /usr/local/psa/admin/conf/templates/custom/webmail/{roundcube.template,roundcube.php}
Rebuild the web server configuration files:
- For one domain:
  
  # plesk sbin httpdmng --reconfigure-domain example.com
- For all domains on the server:
  
  # plesk sbin httpdmng --reconfigure-all
