Bring back support for delegated accounts.
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. :)

The New Outlook for Mac is not accessing the additional authorized email accounts that I access in my organization. These are group email inboxes for which I am able to access in the current Outlook for Mac. When will this be supported? I can't use the new Outlook for Mac if those are not supported.
Have delegation occur automatically without having to add a delegate mailbox manually.
Changing the from address so admins who have access to "send as" Executive users can do it within the client rather than having to be forced to OWA.
