Create Calendar Event from Email Message's Content - Be able to insert a calendar invite into the body of an email that multiple recipitants can click to add to their calendar easily.

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.

The ability to flag outgoing emails for you (as the sender) to follow-up when you are composing them is a key feature of Outlook for WIndows but has never made it the Mac. The workaround of sending the email, then remembering to go to your sent items to flag it does work, but this is an inefficient workflow.

I do NOT!! mean giving the task to another person.
Just link it to a contact and see all the tasks related to a certain person in his contact history.
In an older version this was possible

I use work week and week mode for my calendar and it would be nice if the time was also on the right side of the window. My calendar is *beyond* ridiculous and there have been more than one occasion where I would be an hour off because my eyes accidentally tracked down or up an hour for an event when looking all the way across the window.

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.

Can we please have access to the separate identities in Outlook, the same way Entourage used to? At start up you had a small menu giving the choice which identity you wanted to see. Then if you wished to change identities again, there was a 'switch identity' button under the 'file' menu that brought up the same small menu.

Having to go through the outlook profile manager to reset the outlook default identity every time is very inconvenient!

A feature I found very useful from the PC software was the ability to automatically CC's my assistant into every email that was sent, it owed be great to see this on the Mac version too

Please provide a functionality such as NoReplyAll so that it is possible to prevent forwarding of e-mails.

Reintroduce sorting by Categories and then by Date. This function is available on Outlook for Mac 2011 and the Windows version.

At some point my IT department is going to require me to move to the new Outlook, and my incredibly fragile email ecosystem will have to be entirely redesigned.

When answering a mail you get the text before the NAME DATE and such fields in the preferred language of the user account in macOS system settings.
I know you can change that but having a language setting per mail account would be helpful - could perhaps control spelling and such too. I also know how to change the language for whole Office apps and Outlook with "defaults write" commands.

Its really annoying, that Outlook always forgets the last selected sort by selection when changing saved searches or categories. Its important to search in Work adress books by Company but in Private adress books by Surame e.g.

Please consider a feature request so that one can chose which mailbox is the default sending address in the view at top for all accounts when creating an new email.

As it is now it selects one of the configured mailboxes at random as sending/from address.

Currently, in version 16.16, one cannot change the city the weather feature displays, mine is stuck on Washington. Please add this ability.

The "^[" keystrokes don't work on my MacBook Pro. Another feature that has always existed w/ Windows version.

Remove automatic popover when selecting calendar events.

When looking at the work week in Outlook and selecting an existing event, there is a delay of ~1s after which a popover is opened that displayes some more details. This popover "Steals" focus from the event making it impossible to quickly move or modify the date/time by dragging the node or edges.

This is extremely annoying and makes a common action that previously "just worked" require multiple clicks, waiting for animations and many seconds of interaction.

Allow a CATEGORY ICON [Button] to be used other than having to navigate to DRAFTS. then CATEGORY when composing and sending emails.

allow for a simple short form survey within email, and allow the sender to easily see voting results within the outlook interface. adding links to external surveys has a very low response rate. something simple that allows for a choice of say 5 options would be great. also allow the user to see which recipients have responded.
