Enhanced performance, designed for simplicity – the new Outlook for Mac

I have to say I am utterly confused by Microsoft releasing this "Outlook" preview! 
I had believed the reason for the name "Outlook" was that it was a program that gave you a complete view (Outlook) of your day, week, month, months, year.  It used to do this by integrating mail, tasks, calendar plus on Windows integration to Onenote. Plus giving the ability to integrate all mail types including IMAP and POP3.
This new Outlook is no longer Outlook!  It is a second rate version of mail and calendar.
I believe I have picked up in the forum that the new Outlook does not even connect to Exchange!  Who made that decision!  
Please stop the annoying messages popping up when I launch Outlook, telling me to try the new ill-conceived substandard version until it is ready.  At the moment it is a complete waste of mine, and I suspect most peoples time.  You people at Microsoft only need to read this forum to see what people think is missing.  But then you all already know what is missing.

Please make Outlook what it was originally designed to be.  In addition, I have said in the Microsoft "ToDo" area, The "ToDo" app is a total waste of Microsoft resource, there are thousands of "ToDo" apps, Microsoft should instead integrate Outlook Tasks with OneNote and improve their feature set.
If only Microsoft had put the resource into making "Outlook" exactly what it was named to be, an "Outlook" on one's day, including "OneNote".
I shake my head in bewilderment at the lack of foresight.
There are lots of comments on this forum by people telling us users to look at the "Roadmap".  I have done that and don't see IMAP, POP3 and integration to OneNote even mentioned in design, let alone in development.  From this, I can only assume these features are NOT going to be included.
So, my conclusion to all of this, I can drop my Microsoft Office subscriptions, because it was Outlook and it's functionality that kept me to my Office subscription.  I can, and have already started testing Open Office and Thunderbird and have found it at least they provide the basic functionality I require.  
If someone at Microsoft would care to comment on my thoughts as to why I should remain a Microsoft customer I would be happy listen.  In fact, I would be delighted to learn I am wrong.
