Please make the preview pane appear dark in dark mode. The current implementation hurts the eyes and is woefully inconsistent with the rest of the application appearance.

Add a Recall email option

Please support such feature to be able to see exact address used to send or received an email when either hovering the mouse over the name or double-clicking it.

Archive feature in Windows cleanly allows storage of mail offline in a *.pst file. Archive functionality is missing in Mac Version. I carry 53 GB of mail with huge syncing and spinning issues.

Please add "Recall this message" function for mac！Every time when I would like to recall an email on my macbook, I need to open the Parallels Deask for windows and then open the outlook for windows to recall the email. It is so annoying. More importantly, in "recalling" situation, time is of the essence. In this sense, after I accomplish the two steps aforementioned, the reciever has already opened the mail and I would fail in the recall unfortunately.

We have an office of over 100 employees often sending images between design teams. Our previous email client application had the ability to resize images to lower resolution at the time of sending an email. Without this feature in Outlook we have found more difficulty in our workflow.

Provide conditional formatting functionality that is in the Windows version of Outlook to the Mac version.

Add a cleanup tool in the Mac version to remove duplicate messages in Mac Outlook 2016 like the one available in the Windows version.

Improve rule syntax with AND and OR operations, wildcards for more general matching, and tiered approach for rule application.

Please add the vote buttons. My work uses it all the time and I am left in the dark on my apple.

We store .msg files in SharePoint document libraries and OneDrive, and to my surprise they would not open in Outlook 2016 for Mac.

If there is not a trick to make this work, it should definately be a feature!

Apple has began depreciating older token.d frameworks for CryptoTokenKit with the release of macOS Mojave. At present, Outlook can see the certificates. However after you select them, the changes do not save and returning back to the accounts page shows the digital signing, encryption, and authentication back to "none selected"

Create a rule, which applies to all emails sent on all devices. This rule allows you to select and edit a delayed time.

The new Favorites category in the sidebar is nice, but should also allow Smart Folders to be added as Favorites. I want a few of my smart folders at the top of my sidebar. As do others...there are at least two other feature requests on this page asking to allow the Smart Folders section to be re-ordered higher in the sidebar so they are more easily accessible. Consider adding all those votes up to count for this request, because this request can help solve that problem too.

add voting buttons like PC version has...

We use a 3rd party spelling checker supplied by Druide Informatique with Outlook for Mac called Antidote. Since we moved to macOS 10.14 Mojave, this spelling checker does not work with Outlook. It does work however for Word among other Microsoft applications. Our understanding is that with Mojave, Apple introduced security features that prevent communication between Outlook and Antidote. We see two options: (1) Microsoft “signs” the Antidote connector for Outlook, or (b) Microsoft publishes a new API to be consumed by third parties such as Druide. Would Microsoft consider these options?

Enable auto archive and Manual archive based on user settings option in Outlook for Mac like we have in windows. In windows user can either setup auto archive features in outlook for specific time period or user runs auto archive by just selecting outlook Folder and date under archive tab

add poll feature for emails in Outlook for Mac
