Interested In Using This Configuration?

You will need to install the Cloudoko Driver and Cloudoko Driver Updater software and please also contact us via the Cloudoko Service Desk so that we can re-configure your environment.

The Cloudoko Forms service can communicate with an internally hosted email server with Cloudoko Driver.

Cloudoko Forms communicates with the Driver via a Microsoft Azure service bus relay using transport security, TCP for message delivery, and a binary message encoding. The service bus control channel is SSL-protected. Proven Microsoft technology is employed to ensure security. For more information on Azure service bus relays, see
