Any contact entry added to the Windows 10 People app should be automatically sync with an Outlook 365 address book and vice versa.

TURN OFF HIGHLIGHTED FLAGGED EMAILS

I often write email off hours and want to delay delivery until office hours. Please add an easy option to delay delivery until office hours start.

Under "Quicksteps", add the the following possible actions to the list: "Block Sender", "Block Sender's Domain" and "Report Phishing".

It would be great if Outlook sync'd your email signature across multiple devices so that you only have to set or update it once.

Sometimes you need to rename attachments and the only way is to sabe it to PC and then attach again.

Add "Thank You" and "You're Welcome" buttons in an email, so that when a recipient clicks on the buttons, the original sender gets a brief pop-up text message saying "Thank You", rather than getting yet another email in the inbox that just says "Thank You". And if the email has multiple recipients, then the "Thank You" pop-up text is only sent back to the original sender. This will reduce the volume of useless "Thank You" emails that end up cluttering our inboxes.

The dark theme is great in Outlook, however the inability to change the background and text color of the reading pane make it almost painful.

It would be fantastic to have the ability to configure the default CSS for the reading pain and text/html therein.

Meetings as FYI Only -

Please add a fourth meeting response option such as "Information Only" which automatically responds "Decline" but leaves the meeting info on your calendar. The meeting response would also automatically show the calendar as "FREE" with "No Reminder". This allows the user to change their response without having to sift through deleted emails or respond tentative leaving others to guess as to your meeting participation when you have no intention of going at all.

Create a drop-down list of categories in a contact's card to assign it to a category.

Today we can only chose from "Accept", "Tentative" or "Decline" when somebody propses or invites to a meeting. A lot of times you need to know about the meeting and get the meeting notes but not participate, for ex. for exacuative people, people in a high leadership role etc. My suggestion is that we have a "Decline not participating" option so that we still have the meeting in or calenders, get the meeting notes, updates for next meeting etc.

Add option to email all invited attendees even if you didn't organize the meeting.

Since Januar 2019 we have the calendar options to end an appointment early. It would be nice to also delay the start time by e.g. 5 minutes.

When receiving a meeting invite, the time, date, month and year is shown. But the weekday is not. And there doesn't seem to be a way to easily see this (hovering over the date, or changing a view setting) without opening a calendar. It would be good for the meeting invite to show which day of the week the invite is for, or allow you to 'hover' over the date to show the day.

Sorry to say but don't like the new icons especially the fact that Word and Outlook are both in blue shades they look to much the same when sitting side by side on the Taskbar - which if your background is also blue they just really don't stand out that well. Really they need to be at the least different colours for each Office Icon in order to stand out.

Allow a sort option in the "Deleted Items" folder to sort by the date/time the item was deleted, rather than the original send date. This would allow easy location of recently-deleted items.

When creating an appointment or meeting in your calendar you should be able to create an auto reply (out of Office) associated with that calendar event. That way if you have multiple periods that you will be out of the office you can have it set up without having to remember just prior to the appointment.

Enable default calendar settings so all of the meetings i schedule can end 5 min before the hour or half hour so people have time to transition, think and function during a busy workday!

couleurs différentes pour faciliter l'identification (comme les tabs dans excel)

Allow printing of e-mails from Android smart phones.
