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.

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.

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.

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

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.

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!

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 a Recall email option

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

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

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

After the latest "fast ring" update to Outlook, the badge count/notification of unread emails shows the unread emails in ALL accounts. Prior to this update, the badge would only show the unread count of my primary inbox. After the update, it also shows the unread count in my department's shared inbox. It would be nice to choose which of these behaviors is preferable, as I bet some people may like this change and others (like myself) absolutely hate it.

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

In Outlook for Mac 2016 ver. 16.7.0 when using Google G Suite (google preview) to connect, the function to create folders is not implemented.

This I think is a very essential and basic function that should take priority over other functions in coming releases.

Send a digitally signed or encrypted message for Google Preview accounts

Enable Focused Inbox for Outlook.com Email Accounts

It would be helpful to attach and browse folders that are in iCloud Drive when using Outlook.
