Dear MS, If you wish to replace an application (developed over 20+ years) then make it functionally equivalent.
Until then don't bother with trying to push the turd that is the new Outlook onto people to test.
The new Outlook is on my brand new computer with MS version 11 and no choice for the old, Using the new version I can’t find and miss important email with all my mail being mixed in with the junk mail. It even could not properly read an important email from my brother. Fortunately, I have an older laptop computer with Window 10 using the original Outlook. The new email version that had problems reading an email completely, was handled with no problem on the old version thank goodness. I am going to use my old computer with the Windows 10 version for reading all my email from now on. If MS does not make it possible to revert back to the old version I am going to use another program for my email so I don’t have to switch between computers, or give me the old version back. Your programmers obviously don’t use your email program, if they did they would not have written this useless new version, get a new team or rehire back the old guys to fix he problem. It needs a complete rewrite which will take too long for satisfaction. If you stay with this new version you are going to get a lot of angry users and help your competition. I also prefer Windows 10 and don't like 11,all this is even making me seriously think, forgive me about Apple.
