One would think that Microsoft would learn from previous mistakes, as when they renamed File Manager to Explorer and totally confused the public by using the same name as the browser.  Now they've renamed Hotmail to Outlook, but it's still Hotmail but with a lot of BAD changes that only make it more difficult to use.
Trying to find Help for this so-called Outlook is a chore, and most results refer to the screens of Outlook in Windows Office, not the webmail within a browser. What a idiotic situation.  It required numerous tries and several hours to find the appropriate location for the "new" Outlook help, the "correct" search terms
(if you don't "speak Microsoft" you're out of luck!), and worst, the instruction that actually matched what I was seeing on the screen.  Google finally saved my bacon with its fuzzy logic search.  One of the problems was trying to whitelist a sender (oh, sorry, Microsoft insists on "safe list" and won't find whitelist!), and when I finally found the correct version of Outlook with the correct instructions, the number of steps to accomplish that simple task was ABSURD!  A simple right click on an email address should be all that's necessary.  There have been complaints about that for months, yet no sign of a promised fix!
This nonsense may instigate another hard look at Mac!
