The web based outlook.com and the windows version of outlook 2019 and 365 both support alias support. Only the mac version does not support this. It would be very useful if such support was added.

The ability to customise or use other keyboard shortcut schemes (e.g. Gmail) on the web app makes it 2x faster to process email. Please bring it to the desktop app!

The "Send Availablity" feature is iOS is one of the most useful features I've ever used. I actually switch away from a desktop interface to the mobile version of Outlook just to use that feature. It is that great! It would be AWESOME if the Outlook for Mac team could bring that feature to the Mac Desktop client.

Encouragement... 🤛🏼

Not able to sort by Flag - clicking on column does not work, menu option is not there

Currently, there seems to be a lot of 'dead' space in the new UI. While I like the more modern look, it should be possible to makt certain UI elements a bit more compact, much like is possible on Outlook for Windows...

Have the ability to send an email to a group E.g. Interest Rate Changes and instead of sending emails back have the ability to turn into a chat underneath and in Teams. Like how Spark email does it at the moment with the Discuss email feature.

Would also be good for internal conversations on calendar invites, if someone wants to propose a new time or add info to the agenda. The calendar invite could become a Teams chat and files and chat could start around that meeting.

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.

Conversation threading should be a per-folder setting, so, for example, my Inbox could have it on and my Sent Mail could have it off.

The font size is too large proportionally to all other fonts in the UI.

Adjusting the existing font size setting applies globally and does not address the proportion issue, making the other UI fonts (which are great at the default size) too small.

Coupled with the inability to hide message preview text, the current size notably limits the # of items that can be viewed.

Thanks for your consideration.

It would be nice if this view could be changed by the user. For example at the moment mine shows the event time, the duration, the event name and the location. The location shows the address which takes up 4 lines of type. While this is nice to have and is neatly laid out, my prference would be to toggle the location off with a nearby button or dropdown with toggle choices, to have some choice as to what is displayed here. The trade-off benefit is having more calendar events displayed.

When using Online Archiving it would be useful to have access to the archive policies when right-clicking a folder or email.

In the 'old' Outlook for Mac client this feature was never supported but it is available in Outlook on the Web today.

Support for contact lists from Outlook.com on the web.

I know contact groups (...@groups.outlook.com) are supported, but support for contact LISTS is also needed.

In the new My Day view if you could right click to add events and have the mini-event modal show up that would almost completely eliminate the need to go into the regular Calendar for some of your users.

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.

I would love to be able to arrange my email accounts, like have them in the order I want instead of the automatic ordering from AtoZ.

I'm on insiders fast, on Outlook version 16.33 (1911270) on Catalina 10.15.2, and there's no New Outlook switch, and the option isn't in "Help" either. If there conditions in which it's not available, that would have been good to know before updating to insiders fast.

An account that used for sync - so I "login" to oulook so that preferences and accounts are synced across devices.

Identify which account is the "master"

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

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