Outlook has a few options for sorting your messages, the same way Gmail does. Turn on message sorting to use Focused Inbox From there you can move the window to the right, the bottom or hide it entirely. To turn the feature off - or relocate the Reading Pane - open Settings in Outlook and scroll down to Reading Pane. If you typically use Gmail, you'll be more familiar with a setup with no reading pane. It makes for quick scrolling and less clicking when you've got a lot of messages to get through. The reading pane lets you read a selected message without leaving your inbox.

In Microsoft Outlook, the basic set up splits your screen into three columns: the list of folders such as Inbox, Sent and Junk Mail the Inbox itself and the reading pane.
