Please add the menu bar above emails, so we can easily sort through our tabs - FROM/ SUBJECT/ RECEIVED/HIGH IMPORTANCE/ATTACHEMENTS etc.

The contact within the company had organizational structure within contacts that allows you to look at an individual's direct reports as well well as who they report into based on the Active Directory. The new Outlook design released in Oct 2020 doesn't allow to look up organization. This is still available on the older look in Outlook or Microsoft Teams.

Add a "Send Sent Item To" button in Outlook for Mac

Please add the option to permanently delete emails without confirming

There should be an option to show Titles before name of sender, or at least to give them more prominence.

Most of the time knowing the sender adds very little information, the title is usually much more informative. It's very hard to go through a lot of emails this way.

Even the web version has this feature. Every mail client I remember since the 90s has this feature. From the message I got from support even the mac version had it at some point.

Looking through a large meeting invite it is difficult to get a sense who is invited and who isn't invited. Putting the list in some order would be helpful.

It is way too easy to "un-Star" a favorite.
please make me confirm that I meant to un-star a favorite.

Currently I create rules on the computer that I'm working on but these do not sync between multiple machines. Being able to either add to iCloud and sync with all accounts or even just export the rules to manually add would help

I want to be able to pass the contents of mail messages in a certain folder to a script. I control the script so I can handle them how ever you want to pass them. File handle, stdin, command line option, etc.

Even the option to store that folder in MBOX format so that I could just tail -f the tile would work.

Inline mini translator for Office 365 for Mac. Similar to what you have for the windows version.
The ability to select text in the mail and a hover box appears with the translated text.
I am English speaking living in Germany so this is vital to my productivity.

I occasionally receive emails related to production support tasks which must be acted on immediately. I'd like to be able to create a rule to play a custom sound when I receive one of these emails.

Since I can use rules to mark them high priority, another option is just having a different sound for high priority emails.

It would also be nice to have an option to always play this kind of sound over my system speakers. That way if I'm not wearing my headphones or I step away, I can still be alerted.

Make the new Outlook available to users of Exchange OnPremise again. Or at least: let us know whether it will ever come back or not. I used to work with it just fine (fast insider), and then suddenly the support stopped, with no explanation whatsoever.

I would like to be able to add a room onto a meeting that was created by someone else. It would be useful when a client invite us at a meeting and we have to regroup in a meeting room.

The calendar should appear so you can quickly choose a date, rather than scrolling up and down on days and months. Same for the time... Suggest 09:00, 09:30, 10:00. 10:30 etc.

Allow the "Move To" folder picklist to be longer than 10 folders.

Like windows we need to option to view the OLM files , In windows it can be done just using the Outlook menu : File ->open and export -> Open outlook data files (.pst)
