This new UI is not very functional in my opinion.
In "updating", many of the functions that were used broke. Why can we no longer see titles or links of those in an organization in a contact card? Why was "Scheduling Assistant" and "Tracking" moved to completely different tabs in the calendar? Why was the layout for a meeting invite adjusted? And worst of all - why was "Location" moved to AFTER start and end times making us have to click through all that or move the mouse to type in a location. All these things have done nothing except slow people down.
Simplification is keeping the things people use handy - not moving them! If you want to give people a simplified experience, then let them decide what needs to be in their tool bar. My tool belt is going to be different that then next person. Removing the things I use 50 times an hour because the guy next t to me doesn't just doesn't make sense.
