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

Please provide the unread email count badges on taskbar. It is so useful to know what drops in our mailbox while working on different task in different window. It will save 30 second to 1 minute. You can imagine how powerful feature would be and there is no doubt that a lot of resource hours ( No of current users * 60 Seconds = x number of hours ) can be saved adding this feature.

Week numbers should be configurable to allow them to start based on financial, fiscal or school years, especially as these may fall at different times depending on your country

The option for Out of Office for multiple dates should be available/ to set up an automatic Out of Office message if calendar dates are booked as Holiday. Most people have to book holiday early in the year and therefore already know their holiday dates. They do not, however, always remember to set Out of Office before they go.

Since the last update I can't find how to view the Instant Search again.
Before it was on top of the folder email's list but now it's not, and I can't find a way to reactivate it.
(I had to include it in my direct access in the window title bar)

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.

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

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.

In order to save time it is necessary to be able to put a newly created task into a specific task folder on creation.
So when you're creating a new task you should be able to browse through available folders or create a new folder right from the task creation window. (should work similar to the category setting for a task)

Currently you have to create a task (e.g. by flagging an email message) and then you need to go to tasks and distribute newly created task into a specific folder which is not convenient and consumes additional time.

Allow printing of e-mails from Android smart phones.

I like to have autocomplete but hate the "Other Suggestions". I am unable to find a way to disable that. It is VERY counterproductive, especially for emails that are no longer valid and I don't get option to remove it

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.

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.

Not able to import " required attendees" in appointments from Excel to Outlook Calendar (via a CSV file) Everything works well except required attendees. When I put in attendee's emails they are not loaded into the Outlook Calendar. I want to have attendees listed in each appointmentas well as having outlook send the appointment request to the required attendee, though I am not sure the appointment request is a possibility and would save me time!

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.

generate id number for each e-mail received to use it as reference number at work

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.

An interface for swapping meeting rooms between two meeting organizers who mutually agree to swap rooms. Currently, the meeting organizers have to coordinate an effort to simultaneously cancel and book the desired meeting rooms. It causes anxiety that someone may book the desired room in the few seconds it is free during the swap, and it requires unnecessary real-time coordination for an agreed upon swap.

Since the latest update new email and new meeting are not consistent as to where we write the Title or Subject. It would be better to have the field in the same area as it was before.
