Under "People" the search bar only finds results if searching by name. If you try to search by say, a company name, it will not return results. The old outlook would find results for your search term no matter what field that term was in. Please bring this back!

When sending an incorrect email add the ability to recall that email from all recipients as is possible with Office for Windows client.

Ooops - did we lose the 'Resend' option for sent messages?

When the Agenda/ My Day tab is open, replying to an email somehow forces the window to expand past the edge of the screen and there doesn't seem to be a way to adjust this in the settings.

The ability to transfer a contact in vCard format has disappeared in the new Outlook. Could you put it back?

When clicking 'To Do/Tasks' in the Outlook sidebar, it should open the Microsoft To-Do app instead of opening Microsoft To-Do in a browser.

When composing a mail in a new window (and not in the reading pane) the AddIn toolbar is not displayed. It could be very useful to have it.

Previous delegated mailboxes (or shared mailboxes not sure what you call them) could be added to Outlook and would show up as additional mailboxes.

With new Outlook these mailboxes no longer appear.

It would be great if you bring them back. :)

In current Outlook, my contacts are in the My Computer folder. New outlook does not display them.

How can you design a "New" Outlook that doesn't have same functionality of the Old Outlook.

And when the Old Outlook is no longer an option, how do I get my contacts?

Bad design.

feature to "show all messages from this conversation" is not there anymore

Enable reply and forward buttons for emails sent as attachments. At the moment if someone forward's me an attachment as a .eml file I can only preview it. The Reply and Forward buttons are disabled. The feature is available on Windows and the browser.

Prior versions allowed for Option+click to duplicate Calendar appointments

With the new Outlook i'm not allowed to drag and drop e-mails from one mailbox to another and thus making a copy in that mailbox and folder.

In Outlook, could you pls bring back Connection Status either in status bar or another property in Customize toolbar whether this connection is Online/ Offline. It is hard to see in first sight if there is any network challenge.

Please provide full support for iCloud accounts, as provided for IMAP/Exchange accounts. Thanks.

Right now you cannot add, remove or rearrange columns in People section, and they are automatically pre-grouped in Name (instead of First/Last Name) and Title and Company (instead of 2 separate Columns).
I also cannot sort/search by Category, Title or any other field in the Contact.

The checkmark is important. It gives me some small joy and semblance of accomplishment. Without the checkmark my inbox is just a continuously growing list of questions, tasks and requests that will never appear to be completed. It will just continue to grow and grow and grow. It's the thing of nightmares and panic attacks. Please, let me have my little checkmark.

Outlook for Mac gives ability to custom categorize calendar items by color. This helps me quickly scan my day/week view. However, this function can only be accessed after the event has been created by right-clicking the calendar item and scrolling down to "Categorize". Please review and add! Thank you!!

When Mail is sorted By Conversation and Sorted With Oldest On Top can you please have the oldest mail in the conversation on top as well. Currently the oldest Conversation is at the top but when you open it the oldest email in the conversation is at the bottom! Doh !
