I'm wondering more and more where the feedback for new versions/products is coming from, as I can find nothing on UserVoice that suggests anyone wanted features, i.e. (tasks integration) removed. There also seems to be little user acceptance testing (UAT) being done because these would have been flagged immediately. Cloud-only? How is one supposed work using Airplane Mode on his or her mobile device? It's similar to Kinect for Xbox, is discontinued yet no one thought of how customers will now raise or lower the system volume. Furthermore, discontinuing features or reducing functionality of old ones without a well-advertised pilot program (remember the "public previews" of years past?) is madness! Shunting feedback to UserVoice is essentially consigning it to be ignored by development. All anyone need do is look at the section for Outlook to see this. Users have been clamoring for a unified inbox for years. and there's been no feedback, and the only place we've seen it is Outlook for Mobile.
Meanwhile new UWP apps begin their lifecycles half-baked. Consider To-Do the successor to Wunderlist, just up-dated recently, still has no integration with Outlook, and few of Wunderlist's features. What's up with that? Now it's being done internally with OneNote. Is the end result going to be getting of Outook by having its features divided among multiple apps? What happened to Microsoft's mantra of "Embrace and Extend"?
