Hello Christian,
You can deploy AxCrypt using group policy in various ways, either by way of the setup.exe, or by extracting the .msi setup packages that are contained in it.
However, once installed, AxCrypt will ask for the email to use and then the user will go through the registration process with confirming the email and setting the password to use.
We will soon start development of business related features, and in this situation an administrator can invite users and also waive the need to confirm the email. The user will still have to type in the correct email address and set the password though.
We are very interested in developing as streamlined procedures as possible. Can you perhaps describe your scenario, and how you’d like it to work and we can discuss it perhaps arriving at a good solution for all?
