I am able to see my emails from anywhere, even when I'm offline. It's also very flexible so I can use different apps to access the same data if I want. The app is not as intuitive as other programs I have used but that's because my previous systems were way too complicated for me to learn at first (and I had no support). This program is super user friendly though! Just make sure you know what you're doing otherwise you might get stuck or end up spending more time figuring out how it works than actually using it. Ease of use and flexibility. Accessing emails, calendar appointments, tasks, and contacts no matter where I am.
