Please allow users to choose whether to use Search at the Top or keep the search bar in the legacy location.

The entry fields for TO and CC are taller than the spacing of their labels to the left. This leaves less vertical space for the Subject entry field (both not aligned to its label, as well as narrower than the TO & CC fields), and looks very sloppy. Please revert it to the older format or provide an option to select between the new and old format.

The search box in the latest update covers over the list of emails in the search result with the "recent searches" drop-down.

This is horribly inconvenient, and the search box will be better served by being in the right-hand side where it's not in the way.

Would like to see more color options for themes like the online version has. The limited options all look kind of bleak and don't give room for a personal touch.

Immersive Reader is a cool feature and it is more advanced than the "Read aloud" feature available in Outlook client.
It would be better to have Immersive reader feature available in outlook client too.

In the recent version of Outlook which has the "Simplified Ribbon", it appears that the color of the bar representing "Busy" in the calendar Scheduling Assistant screen has been changed. Busy used to be bright blue, whereas Out of Office was a darker color. Now, with the new changes, as a colorblind person I can no longer tell these two apart. They both look like the same exact color. Now I cannot easily tell when someone is busy vs out of office. Please revert the "busy" color back to a lighter color.

Enable calendar to appear along bottom "Mail" tab. similar to the "scheduling assistant" view you get when booking a meeting with multiple people. This would save screen real estate vs the large "Calendar To-Do" bar, while enabling you to have a quick view of whats upcoming, without needing to go to the Calendar tab.

There should have the option to automatically minimize to tray on launch for Outlook. Most applications have this feature. I feel it is a security risk and also highly disruptive that Outlook pops up on screen whenever it updates while I'm in the middle of coding or trying to have a discussion with a coworker.

For example, with "RSS feeds", "search folders", etc., hide those folders while keeping those functions, make the appearance compact and easy to see

I want to be able to see more than 8 reminders in 1 screen. I know there is a task page in the outlook client, but it is very convenient to be able to see more reminders in the popup window

In every other office 365 application except Outlook, there is the option to add "Paste and keep text only” shortcut to Quick Access Toolbar.

Please make this option available in Outlook.

It would be great to have an option to open the folder where the message is stored.
So you open a message and within this message you can click on "see in folder" like on MS File explorer.

This would be particularly useful for search result lists...

As ultra-wide screens are becoming more popular, it'd be good that outlook allowed to have the email functionality and the calendar functionality side by side.
Something similar to the to-do tab but the real thing: multiple calendars, add meetings, change meetings,...

I am often switching between using my smaller laptop screen when I'm away from my desk, and a larger monitor when I'm at my desk. I have my outlook window set up for my large screen - the folders and calendar panes are switched on, and the size of all the sections is optimised for my large screen. This set up is very crowded on my laptop screen! It would be useful to have a one click solution where I could switch between the views that are optimised for small and large screens.

Add a Share to Teams button in Word, Excel, PPT to share the document in a channel or chat to skip the multi step of saving it on a local drive, then uploading. Additionally saving the extra step of emailing it, downloading it or copying it, then adding it back to teams.

The program should feature the ability to automatically change the theme from light to dark modes depending on a user set schedule or the default time of day (like sunrise/sunset) such as what Apple does in Catalina MacOS and iPhone iOS.

It should allow the option of viewing an email on different size windows. Or Different email viewers. An option to turn on and off dark mode to see how the email looks in dark mode on someone's iPhone.

Since marking an email or message creates a task, I think it would helpful to have a place to leave a notation regarding the task.

I use Outlook on a monitor in the portrait orientation. I would like to put the to-do bar on the bottom of the page.
