At the moment calendar and task-list just can be used in separate screens. It would be very useful to implement both features (calendar & task-list) in the main screen of outlook, where mail view and folder structure is located. Windows-version of outlook already delivers this function by a so called "popup"-function, so please make it possible for mac-users, too. thanks.

Just like the topic says. Make dark mode include the message preview pane. The main interface is nice but the dark mode being there then contrasting with a bright white message preview really hurts the eyes.

I really need to export/import folders and subfolders. This enables me to prune folders by archiving them--and then restoring archived folder if I need them. Have had this capability in outlook in previous version, but not now. This seems to be a regression bug.

Have Outlook added to the 'share' menu (under Extensions) in System Preferences. It's time-consuming, and annoying to constantly have to drag files to Outlook — as opposed to being able to sending them via Outlook under the 'share' option. This is a must for businesses, that email a lot of attachments. Thanks.

I suggest you revert back to the previous look for icons...

Microsoft removed the feature for you to select which Category to show on a Calendar i.e. Grid View. You used to be able to do this by clicking on the Triangle next to a Calendar in the Sidebar which would display all of your Categories. Then you could pick and choose which Categories to display on your Calendar. Now that this feature is removed, you must use Filters, which would be OK but Filters only support List View. Feature removed in 16.19 or 16.20 update.

Indentation is not enough for quoting email text. Not having a clear character as ”>“ (as plain text standard) or “|” (as apple mail) holds me from using Outlook on my Mac. Although it is a really goog email client.
Come on, please!

I just found out that IMAP calendars will no longer sync with Outlook 2016. Calendars are such an important part of business services, I'm not sure why this was removed!

Add ability to snooze messages (i.e schedule messages to come back to the top of your Inbox). Many modern clients support this and it is actually already part of Outlook for iOS. If added, this should be available to use as one of the swipe gestures.

Add support for digital signature and encryption certificates located on smart cards.

We would like to have an option to create a rule to delay all outgoing email, like in Outlook for Windows.
Thye idea is to have a small time to cancel the sending if there is something wrong.

You can delay individual messages, but you cannot add a rule to "auto-delay" X time any email you send.

The Outlook Customer Manager add-on is a great tool for Windows Users. As of Outlook for Mac version 16.20 the add-on is not available in Outlook, and we need this module / app in Outlook

For legal purposes I need to save all emails pertaining to specific real estate transactions their respective FOLDERs in Documents on my MAC. I then download them to a thumb drive and save them for 7 years, as required. About 3 years ago that capability disappeared and I've been stuck ever since.

Really need to be able to configure default views for every app and app section.

I use iOS and macOS outlook, it would be great if the Apple Handoff API was used so I could start a mail on the phone and finish on the mac.

Please make it possible to use Oulook for MacOS with iCloud contacts and calendar. It should be possible by adding support for CalDAV and CardDAV.

I just updated to the latest version of Office for Mac that support Dark Theme in MacOS Mojave. I like using Dark Theme and am excited that Outlook is joining the team, but I am disappointed to see that the reading pane is still in light mode. It is jaring to see the reading pane next to the rest of the program. Is there a way to make the reading pane be dark as well?
