It would be nice if the mobile app inbox folders were expandable and collapsible.

Finding emails under the search feature is painful.
It does not pull in order the most recent sent, received or deleted emails from the person you are searching.
PLEASE fix this. Before Outlook 365 it was easy to search for emails.

So I’m on vacation and need to set up my vacation responder. Currently can’t do it through the app.

MUST be able to search deleted emails. All other folders show up in “search”....don’t leave the deleted folder out...

Add Outlook Notes & Tasks to Outlook Mobile App on IPhone

At least half the time i need to copy paste text, I’m wasting my own time as it fails to generate context options - I’m constantly saving as draft in the hope the function returns

Block directly from inbox junk mail

When I receive a phishing email, I would like the ability to report it to you for investigation and reporting to the appropriate authorities.

Get rid of this and replace with reply forward buttons.
With the latest update the forward and reply and flag buttons are now hidden underneath a separate button. Before there were those buttons either at the beginning of the email or at the bottom. Could you please add that back
Please remember this is for email and not Facebook.

I think it would be helpful if the user could edit the order or Reply All/Reply/Edit Recipients to customize their preferences. Ad an alternative, make Reply the first option.

Please add weeknumbers to calender

I use the “Getting Things Done” method at work and use Outlook tasks to organize my work activities. I create tasks from emails, apply a category, place priority, next items, the whole process. I get home and use my iPad for checking and responding to email and check my calendar for the next days activities. Problem is I cannot see my TaskList and categorized tasks I rely on to manage my day. I really would like you to consider making tasks and categories available in the IOS app to match the functionality of the MS software.

Google calendar allows you to make different events different colors. It’s VERY useful and you should add this feature. They give the option of about 10-12 difficult color options. PLEASE PLEASE add this!!

Telling me an email was received "yesterday" is only mildly helpful. I'd like to know the time an email was received

Have a delay for scheduled outgoing emails

I need to be able to see the shared calendars of each of the Groups that I am a member/owner of. The Groups app is no longer available for many in our organization.

In order to be an enterprise solution it needs to sync all folders.
