In the current version of Outlook for Mac, users can create folders "on my computer" to organise/drag/drop specific emails into. This functionality is not currently working in New Outlook for Mac.

be able to sort searched emails by date/attachments/categories etc as have been able to do in previous versions

Please give us the option to turn off seeing Sent emails in conversation view. I can't stand seeing sent emails in a conversation view. If I want to find a sent email, I'll go to Sent Folder.

Add color coding for Mail account list to easily distinguish between multiple email accounts

"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.

The new Outlook client seems to be limited to syncing six months of email. I can't find the sync limit anywhere. I keep switching between the two Outlook clients depending what I am searching for.

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

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

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

Like Spark Mail, or Canary Mail, the ability to color code email accounts. Would appear color coded in left nav bar and also with an indicator in email list.

Why? Makes it real easy to see what account an email came in to.

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.

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

Add support for voting buttons.

use PST like on windows so there is bettery interoperability and ability to create pst's when archival is necessary.

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

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

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.
