"Install" Outlook for the Web on your computer for the perfect email application.
Those of you who have worked alongside of me however many years I've worked at ICI might find my conversion to somebody who doesn't actively want to fire the entire Microsoft Corporation into the sun as odd. I too am confused by it, and admittedly, there are days (Tuesday, for instance) where I do want put Teams.app in the trash. But upon reflection, most of my Microsoft usage comes from the fact that they simply bought up everything I was already using: Wunderlist became To Do; my beloved coding editor (Atom) was purchased and became Microsoft Visual Studio Code; and Github, the service where all of the web team's code lives was also purchased, though nothing has changed with it (fingers and toes crossed).
The one thing that never seemed to work well was email, on the Mac in particular. For a long time, Microsoft didn't provide an email app for Mac. Then there was Entourage which was about as reliable as Dave's van. In recent years we have been bestowed our own Outlook on the Mac, but it's always had the very distinct smell of what Microsoft calls usability, all over it. Keyboard shortcuts are sparse, and unreliable. Many features (delay send) don't exist. And it is alway dramatically out of step with its web and windows counterparts.
Well, I am happy to report I have found a touch of email nirvana for the last few months in using what is called the PWA (progressive web application) version of Outlook for the Web. Paul, avert your eyes for a minute. By using a chrome-based browser (I am using Microsoft's Edge) you can "install" Outlook for Web so that it becomes its own application on your computer. I find Outlook for the Web to be very usable (threaded emails, loads of keyboard shortcuts, and integrations for many products ICI uses like Zoom and FindTime). and I find the ability to view Outlook as a dedicated "application" invaluable.
If this sounds like your jam, perhaps head over to this page to learn how to install it yourself.
