The Message List details all the individual messages in your Outlook folders; placing a checkmark in a message's checkbox selects that message for inclusion in a message set. The Message List comprises four columns: Subject, Received Time (that is, Date and Time), Recipient, and Sender. Double-clicking on a column header will arrange the messages in alphabetical order; clicking on one of the date headers will arrange the messages in chronological order by that date category. Subsequent clicks of the column headers will reverse the sort order.

Right-clicking on a message, or on a group of messages, will open a Context Menu ("Popup Menu") over the Message List, providing easy access to the commands "Check All", "Check Selected", or "Check None".

Double clicking on a message will display that message in an .html window so you can verify its contents if you need to decide whether a message should be included in a message set.
