I have been working with this product for years now so it is not something new that i am facing however still its good enough in terms of functionality and features. It has very simple UI which makes it easy for users who do not know how things work under the hoods. Good thing about librae saver is that they provide training material to help you understand their products fully before using them at client level. Its an excellent solution when used properly but if your organization does not need secure messaging then better go ahead! We use our emails mostly internally between teams/companies. And also sending emails out from time-to-time (which we dont even pay attention).
