It would be nice if this view could be changed by the user. For example at the moment mine shows the event time, the duration, the event name and the location. The location shows the address which takes up 4 lines of type. While this is nice to have and is neatly laid out, my prference would be to toggle the location off with a nearby button or dropdown with toggle choices, to have some choice as to what is displayed here. The trade-off benefit is having more calendar events displayed.

When a meeting contains a link to an online meeting (GTM, Zoom, etc), display the link in the notification so the event doesn't have to be opened to join the meeting. I'd rather the notification just be native, but if not at least there's a reason to not use MacOS's notification system

Copy paste from calendar items like in Outlook for Windows would be great to have as well in Outlook for Mac.

When clicking button for 'New Event' upper left corner, all event features are available, and default settings from Preferences are followed. However if you double click on a time in the calendar to create a new event, the options are limited (unable to set status as 'Tentative', unable to set Reminder which is stuck at 15 minutes by default--not respecting the Preferences.

Calendar Events function optionally a tasks with completion check marks and/or Completion percentages.

This has long been a feature of 3rd party apps like Fantastical and I don't understand why Outlook doesn't have it yet. It's such a no-brainer and so handy. Right-click an event | Duplicate.

When in the Mail view, the calendar Agenda View list doesn't give any indicator of what's coming up next. If you have 20 items in the day, opening the page or clicking the Today button scrolls to the top of the day instead of showing what time it is and what's coming up next. The Day View has the indicator, but that should be carried over to the Agenda view as well as bringing that line to the top of the list.

There is a preference to hide past items, but this line should appear when showing all agenda items.

It would be interesting when creating an appointment with participants to have the next common free slot as a suggestion

Currently, the Touch Bar controls in Calendar allow you to switch between the Day, Work Week, Week and Month views. It would be very useful to also have a way to navigate between periods (like the arrows that are to the left of the day/week/month above the calendar) in the Touch Bar.

Can't drag to copy between two calendars anymore.
Used to work in classic outlook.

On the new Calendar UI within Outlook for Mac add toolbar options (can still be simplified) but i cant seem to add a calendar category on the fly for instance within the calendar view, i need to open up each meeting - same goes for adding "show as"

I attempted to import an ICS file in New Outlook. I get a view of the calendar item, but no way to "save" it to my calendar. Also, if i "edit" the calendar item, I then get a "Save" button but saving the item doesn't actually reflect on the calendar in "New Outlook". Had to switch back to old outlook to see the item.

A task side bar in the calendar view with drag&drop support to block time to work on a task, like you can do it on outlook.com.

When adding or importing a shared calendar, the categories of those calendar (and their colors) do not show up on "New Outlook". It shows otherwise when switching off "New Outlook" and restarting the app. The categories also show up fine online.

It would be great to create all-day, multiple day events with progress bars indicators or % complete in at least week, month and year views. Kind of shows up a status indicator and user is able to change % complete or incomplete, etc.

Each time when I start Outlook it opens on the main screen with a random size window. Ideally, I would love to see it in the exact same location and size as it was before I quit it e.g. fullscreen on the second monitor.
Thank you.

Add support to end appointments & meetings early (25m / 50m) so you have time to prepare for the next meeting. Already supported by Outlook for Windows: https://support.office.com/en-us/article/schedule-a-meeting-with-other-people-5c9877bc-ab91-4a7c-99fb-b0b68d7ea94f

I suggest that you open all events, meetings bookings in edit (less clicks) mode when you x2 click it
