It would be helpful to either completely move, or at least add a send button to the top bar when composing an email. When all of the actions except send are at the top it seems quite odd and confusing to have to go to the very bottom to actually send a message. Another idea is to possibly shrink the composure box so it isn't so far away.

After pressing the tab key to go out of the Subject field of a new email, please focus on the body of the email, not the Font and font size.

Current tab-key sequence: To --> Subject --> Font --> Font Size --> Body
Suggested sequence: To --> Subject --> Body

"View Source" was an important tool for looking at the source (headers, body, servers, etc.) of a received message. It was in the context menu (right-click) but is no longer there. I could not find it in the menus either.

Ooops - did we lose the 'Resend' option for sent messages?

When sending an incorrect email add the ability to recall that email from all recipients as is possible with Office for Windows client.

With the New Outlook for Mac, you seem to have removed the functionality to right-click on an email and set a reminder/flag/due date for a mail item. Can you please return this functionality? I found it especially useful for items that I could not act on at the moment but needed to follow back up with.

I know I can tap in open in new window, but having to press it everytime is tedious and prone to mistakes

Outlook for Web condenses the conversation nicely; expanding only the most recent message and giving a preview of the others. You can then expand each previous message separately if you need more context.

I LOVE the Outlook web app and want it as a native macOS app.

Add support for voting buttons.

In Outlook for Windows I can add a send delay to every message as a rule. I like doing this because it gives me an extra minute or more to change my mind about an email after clicking 'Send'.

The web version offers a 10-second delay, which is even better than nothing.

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.

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

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.

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.

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.

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.

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.
