Literally can't even use the new Outlook now since we rely on this

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.

Add support for voting buttons.

Allow Embedded Outlook Messages (.msg files) to be opened in Outlook for Mac. Colleagues regularly forward embedded emails that I can't open

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...

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.

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

There's no way to access the Address Book with people on your server anymore.

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

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

It will be very useful to integrate a button that, while replying to a mail, send a message and archive all the thread.

I suggest that you open all events, meetings bookings in edit (less clicks) mode when you x2 click it

I like having the left sidebar collapsed as it reduces wasted screen real estate. However, I occasionally need to access other folders like Sent, Archived, etc which means I have to collapse and expand this sidebar every time to see those items. It would be great to have another method of switching folders while keeping this sidebar collapsed.

Note: this should also apply to calendars, people, notes, and tasks.

Skype integration into the meeting creation tab was one-click and easy to do.

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.

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

So far hasn't done anything useful to my search results, and is just extra clutter
