Sum up meeting hours in a calendar period (week, month, etc.). Allow user-defined metadata tags on meetings to sum hours by project/type/etc.

You can not see and change the calendar in a open appointment. So if the wrong calendar is selected in the side bar (when you have multiple share calendars e.g. in google) you can not change this without deleting the original calendar item

currently it shows unknown availability for organizer. Have to add myself to the invitees to see my availability.

When I accidentally schedule a meeting in the past I'd like to be notified of it so I can correct the date and time if needed

The suggestions for recipients list doesn’t show the full name. It’s hard to find the conference room that I want.

When prompted "Microsoft Outlook" would like to use your current location add also the "Always Allow" button

Please add the Meeting Room Permission as in Outlook for Mac. Thank you!

since i've had the Mac, my calendar events no longer change my jabber status to busy/on a webex, etc.

Please allow the recall of reminders, in case of an accidental dismiss.

When an upcoming event is X minutes out (user gets to set how much time) the event's highlighted line in the reminder window will flash, blink, or pulsate, etc. (again, user gets to decide style of blinking and color).

When booking or viewing an appointment, the date shows in the local short date format. It would be useful to have the day of the week also - for example Friday 14/06/2019, as often the day is a big decider on whether an appointment is possible or not.

When making an appointment in the new outlook experience, there's no option to control the reminder time, which is something I often change depending on the type of meeting/appointment.

This is available in the Windows version of Outlook.

When mousing over an calendar entry, the following informations are shown:
- subject
- date & time
- that i am the organisator
- the place, where the date is
- and when the alarm comes

It would be wonderful if, maybe the first 3, participants can be shown as well.

When I double-click on a calendar day to create a new appointment, the current default is to the comment area which means I have to manually click in the Subject to type the name of an event. Please change this so it defaults to typing in the Subject area instead.

When syncing your planner items it would be nice to have a rich card displaying the planner information directly within Outlook instead of having to click on the link to interact with the card.
