I have third party applications that consume ics files. I need to be able to generate/view these file

Calender export function would be great!

We work night shift and graves, outlook will not let me schedule Our shifts, 4:30 PM to 4:.30 AM. Pop up box says, "The date you entered occurs before the start date". I get it. But there is not even an option for it to be set from 4:30PM to Midnight, than Midnight to 4:30 AM. I'm here for the whole shift and if I don't change it on the calendar it gives the false impression of when I am and when I am not available. Plus getting scheduled for a meeting when I should be sleeping is a pain!!

Shouldn't my outlook.com calendar basically mirror my calendar on Windows 10? If I'm signed in under my Microsoft account this stuff should be identical across platforms.

Family calendar is a great option but needs to be more flexible. Please enable editing rights in Outlook desktop and enable integration with third parts Android App (for istance: Calendar Widget Apps). Thanks.

Family calendar is broken! I add an event to it from outlook web and it can either create it and disappears shortly or output an error message with no description. The same is true for outlook app for android.
What the ****? This behavior is not acceptable, is just bad software. I'm thinking to switch calendars to a competitor....

The button to add a skype meeting to a calendar invite seems to have dissapeared in Beta. Please add it back again.

Please allow me to switch "Agenda Pane" on or off in "Settings." I know a lot of people like it but I don't use it and it makes my calendar too narrow. It is especially annoying when it opens just to tell me I don't have anything going on that day. I am smart enough to read my calendar and figure that out.

For the outlook birthday calendar please add an option to change the default reminder on all events.

Allow to change color of group calendar in the new Outlook view. Currently, the colors are automatically chosen.

Outlook account doesn´t sync with Samsung calendar app. It NOT possible write an event and keep it sync in cloud. I pay to use outlook, support to client doesn´t help me with. The answer was Download Outlook app. Outlook app isn´t good at all like Samsung calendar app is.

Please update Office 365 for MAC to allow import of ICal

Very much dislike the new mail pop ups. Return the mail system to what is was with the email reminder capability.

In my calendar 3 birthday events are created for the same person. There is no information what is the source of this events. like it is coming from People information. And there is no option to delete those events from birthday callendar

Transfer Meeting Ownership.

Often, I create meetings for projects, but then I transfer project ownership to someone else. Rather than having to cancel my meetings and have the new owner re-create the same meeting, I would like to be able to simply transfer ownership for a seamless integration.

The beta Version of Outlook.com Calendar in weekly overview shows the days of the week all differently wide (current day broadest, next day second broadest, day before very narrow ...etc.). I can not describe to you how much I hate this ugly and very unnecessary feature. What is worse, I can't change it in the settings. So, because I want the week days to be displayed with even width like a sane person, I have to go back to the old version.

Please allow manual enter of dates -> being blocked from just typing makes looking at previous dates in the past painful when forcing users to have to use the calendar arrows - or see gmail how there search adds the data to the search text and you can edit it there.

I need to be able to invite people to my auto-generated calendar invites. Example: Outlook made a dinner reservation on my calendar, but I can't add my wife to it..... grrrrr

In my outlook.com the events stays in the calendar for some months, and then disappear. For me it would be great to have all old events still.

Try the beta is a trick, we can't go back to classic. There was a post about this and it was locked. The new calendar is useless. It has a lot of un needed features that slows down the usage to the point it is not a tool that help increase productivity anymore. It is also full of bugs. At the very least you could let us go back to the classic Calendar.
