Change the look of your mailbox in Outlook.com and Outlook on the web

From here you edit a number of settings which change how your mailbox is displayed.

1. At the top of the message list, select Filter.

Display density lets you adjust the spacing between messages in your message list. Under the View tab, choose Density > Full to view sender images, attachment previews, and message preview text (sender, subject, and part of the first line of text). Medium shows only message preview text with some spacing between messages, and Compact shows only message preview text with minimal spacing between messages.

When Focused Inbox is on, Outlook automatically sorts messages in your Inbox into Focused and Other tabs to help you focus on what matters most. If you prefer to see all your email messages in one place instead of having them sorted into Focused and Other, select Settings  then Mail > Layout. Under Focused Inbox, select Don't sort my messages.

You can configure the Reading pane by selecting the View tab > Layout > Reading pane and choose Show on the right or Show on the bottom. If you don't want to use the reading pane, select Hide.

To learn more about dark mode, see Dark mode in Outlook.com and Outlook on the web.

Conversation view groups your messages by conversation. To modify your Conversation view preferences, select the View tab. Under the View tab, select Messages > Conversations and choose between Group into conversations or Show each message separately.
