Put the menu back at the side instead of in the middle where it's necessary to move the mouse half way across the screen to use the menu.

Put contacts back where they were.

Get rid of Starred and Unread and show Spam and Deleted Items.

Get rid of the blank line above and below Views.

Get rid of the blank line at the top of the email which can't be used or deleted.

Easiest way out is to return the previous version.

Everybody hates this new version.
