the search menu of old Outlook allowed for searching and/or filtering on many options — has attachments, is flagged, and so on. it’s kind of useless not to be able to search for flagged messages.

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!

Please can you enable the ability to swipe through tech calendar in the same way that you can with the default Apple calendar

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

Add Microsoft Teams to quick entry in the Calendar

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.

Unread email counts don't appear next to folders unless the folder is opened.
This is a crucial feature, as I'm missing emails sent to me.

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...

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 actual Teams status e.g. of an internal email recipient doesn't show up anymore. All user appear as offline now. I guess this is a bug to be fixed.

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.

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.

I suggest you add a button to create a task from an email body that is highlighted. When a text is highlighted you should be able to create a task quickly from there with being able to link back to the original email as a reference.Inviting people to a task would be a nice touch as well.

It would be good to bring back the ability to resize columns in "New Outlook" since I'd like to see more of the message title and less of the sender.
It would also be good to be able to change the colum order, or move the delete/archive flag column back to the left. In the current order, I keep accidentally deleting messages, something I never did when that column was at the left.

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.

On MacOS you've standardised keystrokes when moving the cursor or editing text. It's very inefficient and distracting, that Outlook is not following this standard.

One example:
System wide you can use Ctrl-a to jump to the beginning of a line
In Outlook it selects all text. -> Very problematic for people who can write fast.

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 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.
