So far hasn't done anything useful to my search results, and is just extra clutter

We know that the unified inbox is coming back but it's really important that we can set it as the default view when Outlook in launching.

This feature is really simple but very important. It was missing from the last Outlook on Mac.

Please. Add it.

Would be great to have account support for email aliases per provider.

Outlook for Web condenses the conversation nicely; expanding only the most recent message and giving a preview of the others. You can then expand each previous message separately if you need more context.

I LOVE the Outlook web app and want it as a native macOS app.

use cache exchange mode to download mails to an OST file.
Currently user are downloading everything.

I keep a pretty clean inbox, and while I like the overall design of thew new Outlook's Inbox area a lot of screen space is wasted to these "This week", "Last week", etc" identifiers that are just not needed.

Please let me turn them off, like you could in old Outlook (via unchecking "Show in Groups" setting).

When the notification window is displayed for new incoming email, please include buttons to quickly archive, delete, or flag the new incoming email without having to go to the main outlook window. It would be nice to be able to quickly delete incoming email if we don't want to read it, right from the notification display.

The ability to customise or use other keyboard shortcut schemes (e.g. Gmail) on the web app makes it 2x faster to process email. Please bring it to the desktop app!

On MacOS you've standardised keystrokes when moving the cursor or editing text. It's very inefficient and distracting, that Outlook is not following this standard.

One example:
System wide you can use Ctrl-a to jump to the beginning of a line
In Outlook it selects all text. -> Very problematic for people who can write fast.

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.

use PST like on windows so there is bettery interoperability and ability to create pst's when archival is necessary.

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.

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.

Was previously able to use an alias on a Gmail account, no longer able to do that on the new Outlook. Love it but this was an important feature. Can you restore?

In the mail view the folders on left does not remember the width setting and needs constant resizing to see the folders

When I'm searching sent mail, I NEVER need to search on the From: message, and am ALWAYS looking for a message I sent to someone. I'm sure there are exceptions to that for some people and accounts, but in general, that would be the intelligent field to be searching for when in the Sent folder.

Please provide conditional formatting support just like Windows version. Would like to mark incoming mails with colors based on categories/rules

Add a Clean Up feature as the Windows version currently has to clear up any duplicate emails/unnecessary emails from conversation threads.
