It is easy to use, it has many features that help with organization of tasks at work which makes me feel less overwhelmed when I have multiple things going in my mind or need some time for myself during working hours. The fact they are not open 24/7 would be something i dislike about this app but if u dont want an interruptive phone call while ur doing your job then its one solution out there as long as we trust them enoughtly. Its great because now all our emails go directly into inboxes instead wasting everyone's precious memory space by sending those mails twice (once through email client & once via outlook).
