Using New Outlook on Windows for professional communication and productivity
New Outlook, has limitation and does not do many things that Mail can. If MS decides to stop supporting Mail without including requested options which were availible in the Outlook and Mail it makes no sense to use an inferior unstable version.
The new Outlook is still under development: not everything works yet
There are lots of settings that are available in the options in classic Outlook and MAIL, but are missing in the new Outlook.
Another particular problem is that the new Outlook no longer allows multiple mailboxes to be merged into a single inbox, which makes managing multiple email accounts considerably more difficult.
If MAIL is phased out without NEW Outlook having the options I need, I will be forced move my computer to Thunderbird email and eventually away from all Microsoft products all together. There is a large group of Microsoft users that will be doing the same. I am not sure what Microsoft is thinking by rolling out a product that is underdevelopment, I don't want to be a beta tester when it comes to something as important as emails when there are many other apps that can do emails far better and are stable.
