allow me to read all of my mail just by tapping the spacebar

In reading pane able to choose more lines to pre read a message.

Light and Dark mode are great but it would be nice to have some additional customization.

currently have to download each attachment individually. Would be nice to have a download all option

Just like Apple Mail, it would be nice if the reminders created from Outlook through share function could have a link back to the Outlook message, just like it happens on native Mail app.

In the latest outlook web access pressing "C" while on any email instantly brings up a dialog box to categorize that email. The dialog box is even smart enough that if you type any text of the category it truncates the list. To do this in the desktop app requires many clicks - very inefficient.

Under the custom options for reoccurring appointments, it would be nice to see hourly as an option. I have multiple tasks that need to be completed every 6 hours, and others more frequently. Currently, I have to create multiple appointments per day and set them for a daily reoccurrence. It would be nice to only make 1 appointment and set it for x hours reoccurrence.

FOR Exchange Online-backed accounts - would it be possible to allow Outlook to provide the 14-day reminders prior to password expiry?

Our Mac endpoints are not domain-bound and I get frequent requests from end users who don't spend any time in the web applications for a reminder prior to their O365 password expiry.

Outlook for MAC

In several versions back, I requested to bring back highlighting emails that contain same subject when not using conversation view. It got several supporting comments, but eventually got a response of something like, not in the direction we wish to go.

Currently, you can only manage one issue at a time. SO if you have an unresolved issue, you can't report a new one via the in-app reporting. This is suboptimal, especially for those on insider builds.

There was a really handy ability in scheduling assistance to add multiple rooms at ones and have an ability to understand its load / when meeting start/stop, etc.
Please bring that back. Adding one at a time is way too complicated.

I love the new simple UI. Please export to the rest of Office for Mac.

There does not seems to be an intuitive way to clear a search and have Outlook display all items. I cleared out the search bar at the top of the window, but Outlook still only displayed the search results.

I've noticed some of my emails were disappearing when I clicked on them. I found out I would by chance quickly click where the trash can icon was and delete the email. Can that somehow be changed, removed from that location?

I regularly operate between the Windows and Mac version of Outlook, would love to see the category colors be consistent between the two worlds

Please give printing an overhaul too.

Kill the Page Setup menu and make the print dialog work like the default macOS print dialog where the Page Setup settings are in the print dialog.

Perhaps correct scaling of mails could be fixed too. Mails with wide embedded images and some HTML mails, don't scale to fit the page nomatter what we do. The right edge is cut off.

Printing the same mails from Apple Mail woks fine,

UI

The distance between the folder names at the left pane is too big and the font must be customizable

Me as a user I want to have all my emails available in my client not only a small subset. Despite that I do want to have the option to synchronize down all items.
