1) Allow for categorizing email in Outlook on iOS.
2) Show categories assigned in desktop client.
3) Allow sorting by category in Outlook on iOS.

Create, Edit and Delete Folders.
Auto-collapse folders in the side bar when the list is too long.
Arrange order of folders

It would sure be nice to have the option to change the sort order in which the emails appear within the threads. I, for example, would like the most recent email to show up at the top of the list. Currently the most recent email is showing at the bottom.

The new navigation pane doesn't allow customisation of the initials in the circle. With multiple accounts in outlook it's impossible to tell them apart.
Let users set a custom account avatar.

It should be possible to synchronize Outlook with Apple Contacts, including iCloud contacts and to import Mails and folders from Apple Mail.

The Outlook app takes a long time to work each time when changing between apps. This is the case even when the app is already open. The screen is blank for ten seconds or maybe longer before it loads. Compared to accessing the Exchange server through the native iOS Mail app, which my company disabled in the past year, performance has been slower and sluggish.

Ability to customize the sounds and volume for notification alerts, just like Apple Mail.

Set dates and times when you will not receive notifications.

It would be great to have my notes in my Exchange account can sync with my Outlook.

Allow users to only sync selectively from an account (ie, ONLY Mail, Only Calendar, ONLY Contacts, ONLY Google Drive and not email...) as opposed to having to sync mail, calendar, contacts as a whole.

Allow users to only sync some folders.

The ability to see rules and create rules for an entire domain. I frequently have emails from users within my domain that make it into the non-focused inbox.

I would like a way of forcing all emails from my users into my focused inbox.

Delete PDFs, jpegs or any other type of file in files section

Also, delete entire file folders

It would be helpful to see the unread message count for each separate account on the accounts menu in mail view.

Please please please can you make it possible to define what an individual requires in terms of their default outgoing mail FONT. When composing an email using outlook the font appears to be cambria or similar - and looks awful. Many thanks.

It would be nice to be able to control what types of items create notification banners/alerts. For example I only want to see calendar reminders but not an alert for new emails.

Being able to change, edit, delete your profile picture on your mobile app

Hi, I'd like to be able to delete autofill addresses. For example, I accidentally used an old address for my wife. The address is no longer valid but it appears at the top of my autofill list thereby inviting errors by my clumsy fingers.
