I don’t want to send my message securely, can I temporarily turn Mailock off?

Yes you can.

When the Outlook add-in was installed, you may have noticed that a Mailock button appeared in the ribbon in your Outlook email compose window.

This button will be blue when you are writing a secure email and red when you are writing an unsecure email.

Simply click the Mailock button to toggle between the two operating modes - red to disable and blue to enable.
