| As you receive messages, you can use pre-defined standard arrangements, such as grouping messages by category, flag, and importance, to help you view and manage your messages. If you exchange a lot of e-mail regarding a specific topic, you can group messages in an e-mail conversation together to make it easier to find and respond to conversations. You can use the expand/collapse button to display the entire conversation. In previous versions of Outlook, message headers appear in a single line. In Outlook 2003, you can choose between a single-line or multi-line layout, which displays the From, Subject, Date, and Icon fields in a vertical column. Arrange Messages -
