In Outlook 2016, there is this huge gray bar at the bottom which lists (in a very big font) Mail, Calendar, People, Tasks, etc… to switch to their corresponding folder.

In previous versions of Outlook, they were listed as icons within the pane on the left which also displays all your folders.

I liked this configuration better as this was a lot smaller and therefor allows for more space to display the message list and also gives me a larger Reading Pane area.

Is there any way to put it back there and gain back some of this wasted space?
