In the old version of Outlook (although it only ever worked sometimes) you could highlight text from an email you have received, and reply to it, this created a paraphrase of that text in your response. This is the most useful feature of Outlook for me.

Now with your refresh, you cannot do this...useless

In the attached file preview screen, it is difficult to know the position of the x button for closing. It is easy to understand if it is in the upper right of the preview area, but there is an x button in the upper right of the message on the right of the preview area.

I liked the bigger difference in font size between the subject & sender in the old vs. new Outlook.

Be able to exit out of calendars at top of interface. And please add the option to arrange calendars in alphabetical order :)

The "view all proposals" option is missing when someone counters with an alternative meeting time in Outlook online.

For the browser version - The attachments in the calendar events don't load right away, you have to open the calendar event twice for attachments to show up. It's super annoying. For the app version - there are no paper clip icons to show there are attachments in a calendar event.

Group the emails by conversation. Allow the whole message to be seen in the readying pane. I have tried everything, and the only way to read the whole message was to revert back to the old Outlook. There was no way for me to alter the reading pane, so what is the point in that! The old system had the ability to scroll left to right in your message, to read it all, that facility is needed in the new Outlook.

Text harder to read for my dyslexia

make all type darker, Gray type doesn't work, or give me the option of making it darker.

There is an irritating glitch which occurs when you hit "reply or reply all" and instead of allowing you to respond. The whole email chain collapses in on itself. There is no reply message box. Even when you refresh the page it will not work. I have to return to "Old" outlook to send the response message. Please fix!

you need to make it so that you can see what you are typing

With new outlook, I don't know where to check who accept calendar. Very annoying.

can you please provide the results of a search in chronological order from more recent to older messages

On the old outlook, when selecting the check button to select a certain amount of emails (ones on the screen at the time) it made things much easier when trying to delete and organize. Now when i click the check button it selects ALL mail, which is frustrating when you want to delete more than one.

I like the option of split calendar view in the new version as it allows clear viewing of others' calendars.
However, in the new version, the list of people isn't available on the side to click on to view their calendars.
Also, there's no option to set permissions.

I didn't find the CTRL+E (aka search) feature...

I want to use "Fine email" when on mouse over.
