Message Content
Having performed a search to display a list of results, the content, properties and attachments for the current message (i.e. the message that is highlighted in the results list) are displayed in the message pane, at the bottom of the search window. The same information is shown when a search result is double-clicked and opened in a new window:
Content for the message is displayed in the message tab, properties are displayed in the message properties tab and attachments are shown in the attachments tab (if present).
