"New Outlook" appears to not have smart folders. I have critical uses for this.

Right now all sub-folders including sent items show up by default making it very long list for each email.

Mirror Windows version function related to "After moving or deleting an open item" and the option to return, open previous or next. Also, add previous/next buttons to email windows.

Just like on outlook.com it would be nice to be able to pin messages at the top of folders and sync whatever message you pin in outlook.com to also pin it on the app.

feature to "show all messages from this conversation" is not there anymore

Please consider making the number of months in My Day configurable so I can show 2 months at once.

Currently, My Day only shows one calendar month. This is annoying, especially during the last week of a month when you might want to check appointments for the following week. Having the option to see further in the future without switching to the calendar view would be helpful.

When I'm searching sent mail, I NEVER need to search on the From: message, and am ALWAYS looking for a message I sent to someone. I'm sure there are exceptions to that for some people and accounts, but in general, that would be the intelligent field to be searching for when in the Sent folder.

When clicking button for 'New Event' upper left corner, all event features are available, and default settings from Preferences are followed. However if you double click on a time in the calendar to create a new event, the options are limited (unable to set status as 'Tentative', unable to set Reminder which is stuck at 15 minutes by default--not respecting the Preferences.

Ability to add columns such as Message Size. My organisation has strict quotas so its handy to be able to delete large messages

I attempted to import an ICS file in New Outlook. I get a view of the calendar item, but no way to "save" it to my calendar. Also, if i "edit" the calendar item, I then get a "Save" button but saving the item doesn't actually reflect on the calendar in "New Outlook". Had to switch back to old outlook to see the item.

In many forums (including standards and open source) bottom reply is preferred where the previous message is indented with chevrons (>). However Outlook for Mac forces top reply. This makes it incompatible with the community standards of the web.

Outlook should support an option (like it does for attribution at the top of the email) that enables quoted reply for html or text messages. Specifically, switching from html to text message should change the quoting from the blue bar to the chevrons automatically.

Copy paste from calendar items like in Outlook for Windows would be great to have as well in Outlook for Mac.

Please add the feature to use CalDAV- and CardDAV-Accounts for third-party calendars and addressbooks synchronization.

On the new Calendar UI within Outlook for Mac add toolbar options (can still be simplified) but i cant seem to add a calendar category on the fly for instance within the calendar view, i need to open up each meeting - same goes for adding "show as"

A task side bar in the calendar view with drag&drop support to block time to work on a task, like you can do it on outlook.com.

New message, meeting should be in toolbar like in web client (these things should really be consistent).. it's much better to put all operation in the toolbar instead of randomly splitting this one off and segregating it by itself in the blue area... took me 5-10mins to find it 🙁

New Outlook doesn't send email when using "share document" option through Office Mac Apps
