I just really miss all the good stuff from Windows Mobile 10! There are MANY things I'm missing, but in this case Outlook. Calendar and Mail. It was great the way it was! I don't like the white colours for Android, prefer Dark Mode and, sorry to say, I hate the look of the calendar. It's so messy and was/is so much better on WM10.

that will make the search more easy also if you single email from one thread is being flagged, it won't flag all the emails on that thread. Also the emails would appear distinct and not clubbed all together

-Choose Pull vs Push
-Schedule Sync
-Sync settings per account/per folder
- Display date/time of the last synchronization

add to block list button

Add button to report EASILY spam and phishing, it's a need! like it exists on web interface

I want to delete all my emails once

Print from open emails within outlook.

need to have a monthly calendar view and also a widget so it can be on your home screen so you can see it immediately

I set up a signature on my desktop and I need this to also be synced as an option on the mobile app. It should not be necessary to recreate the signature.

make it possible to select an individual color for the accounts instead of automatically assigned color. and make it possible to have a picture instead of color+letter.

Your native calendar widget is ugly. Either provide more choices or allow us to sync with Google calendar seamlessly instead of having to export entries and manually sending it to Google calendar.
