Move and copy messages between accounts in Outlook for Mac

It would be great to see this feature in Outlook Mobile on iOS.  We have a process which a majority of our employees use where they file messages into a Shared Mailbox for team members who were not copied to have access to the original message.  It used to be possible to add a Shared Mailbox to the iOS Mail app, but Apple seems to have changed something along the way and we cannot make this work the same as it did long ago.  Outlook Mobile would be a great place to have this feature come back because it is so easy to add Shared Mailboxes in this app.
