As of the June 8, 2020 release you only support Microsoft and Google mail accounts. Seriously? Please add back support for any standard IMAP account. This change makes this Mac version pretty much useless if you don't have one of those mail accounts.

Version 16.32 (19110600), cannot open shared calendars, for individuals or resources (e.g. conference rooms). Views are confirmed to be visible via O365-OWA.

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.

Previous delegated mailboxes (or shared mailboxes not sure what you call them) could be added to Outlook and would show up as additional mailboxes.

With new Outlook these mailboxes no longer appear.

It would be great if you bring them back. :)

With the new Outlook i'm not allowed to drag and drop e-mails from one mailbox to another and thus making a copy in that mailbox and folder.

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

Currently have to use VoiceOver previous item / next item while adding search terms. When hitting tab, VoiceOver should announce the search field one is adding terms too.
