Right now all the panes are quite large. Right now I pretty much have to use Outlook full screen if I want to get the folder list, message list, message body, and My Day all on the screen without having to do a ton of scrolling left and right on the message. Not sure if this should be fixed with the ability to change the font size in the folder list, auto-resize the calendar widget as we shrink the column size, a combination of those, something.

I would like to turn off confirmation when deleting from Junk folder. There does not seem to be a setting for it.

Option to make it permanent. Why does it go away?
It's a pain to have to enable this every time I want to look at junk messages. Should behave as the other folders.

It would be interesting when creating an appointment with participants to have the next common free slot as a suggestion

Literally can't even use the new Outlook now since we rely on this

So far hasn't done anything useful to my search results, and is just extra clutter

I never work in the "all mail" view in Inbox, but mostly the "unread" or "flaged". Everytime I move "in and out" of the inbox, the view is reset and I have to select the view again. Please make sure the "setting" for the view is keept.

When 'Reading Pane' is selected as below, 'Delete', 'Archive', 'Flag' buttons are too close to the mail, which leads to accidentally deleting mail when clicking to read. Provide an option for the user to change the position of these attributes or move them to the far left of the mailbox

Please provide conditional formatting support just like Windows version. Would like to mark incoming mails with colors based on categories/rules

In conversation view, when there are multiple unread mails, when tried to view, it goes by default to the latest one. Earlier it used to go to the first unread mail in that conversation

Currently, the Touch Bar controls in Calendar allow you to switch between the Day, Work Week, Week and Month views. It would be very useful to also have a way to navigate between periods (like the arrows that are to the left of the day/week/month above the calendar) in the Touch Bar.

I sorely miss the Tasks pane from the Windows version of Outlook. This was such a messy, but useful feature that helped me organize projects and keep track of important emails. I would love to have this feature back on the Mac version. Having to switch between a Tasks tab (like Calendar) is not the same and less useful as I fall into the Out of Sight, Out of Mind trap.

Add support to end appointments & meetings early (25m / 50m) so you have time to prepare for the next meeting. Already supported by Outlook for Windows: https://support.office.com/en-us/article/schedule-a-meeting-with-other-people-5c9877bc-ab91-4a7c-99fb-b0b68d7ea94f

Add support for voting buttons.

In the mail view the folders on left does not remember the width setting and needs constant resizing to see the folders

Love the new MyDay but would be even better if in Day View an empty day auto closed the panel and visa-versa.
