Color Categories for Outlook Calendar are gone in the Beta. The new version doesn't offer giving appointments within the same calender different colors (categories). That was always one of the major reasons I used Outlook. If that is gone for good, I might as well use Google Calender. :-(

I HATE all the colored circles. How do I remove the?

As a basic functionality, add a feature to see which email address the message was sent to. Right now, when I hover the mouse over the recipient/contact name, Outlook gives me all the Contact info, with ALL the person's email addresses, so it is not clear which address was used. This is BASIC stuff!

In the desktop Outlook application, I can right click on a particular email, Follow Up -> Add Reminder... but there is no such thing in the Outlook.com. I would love to have this feature implemented. I am using this feature all the time in the desktop version and if I'm going to use outlook.com, I need to have this feature there as well.

We hope to add a new function to outlook that can create a custom schedule in calender.For example, We want to use for an irregular meeting with different days of the week or time.

Because it is inconvenient for the following reasons.

If participants are added, it will be necessary to change the contents again in all meetings.

Also, "Notes" has a custom schedule function and Irregular meeting can be set up.

the block button is missing, put it back!

I work as part of a team in work and often by myself.

I often have overlapping events between both calendars. There should be a way to add an event to more than one calendar at a time. Currently I have to add to my personal calendar and then re add the event to my team calendar.

Why is it no more available in the new version to report any spam, scam or fishing?

When I write 'Marathon' as title of an appointment, the shoe is introduced as pictogram (even though it is a skating event ;-) ). When I click to insert a pictogram, I doe not see the shoe. Bug? Do we see all the possible pictograms?
Could more pictograms be added?

stop logging me out of my account without my request or permission

The recent folders list is suddenly so much shorter in this new version of outlook, so it takes way more time now to search for the right folder. Please make it as long as the classic version again

Authenticate each email.

I would like the option of requesting 'read' and 'delivery' receipts from outlook.com please.

we would need to have the option to set up read confirmation for all emails.
in a general way

I'll keep on dreaming that some day the 'mark as junk' function will actually work, and as intended, on Outlook for Android, without any detour via Outlook.com ….

Ability to connect to external contacts (Facebook, etc)

There is no way to share screens during Skype sessions initiated through the icon in the calendar. If you want to share screens, you must open up the app and use that instead.

Please allow a PERMANENT (until re-configured or re-toggled by the user) elimination of the reading pane. I hate the clutter. I only want to see contents of an individual email if I click on it. I hate having to eliminate the reading pane every time I launch outlook.

we need to keep "bloquer" block for some emails...
