The columns displayed in the list can be adjusted by clicking the List Options icon in the leftmost column of the message list header. This opens a dialog where you can select which columns to display and how to sort messages. Click Save to apply the changes and to close the dialog.
Note
The “From/To” column is a magic column that displays the sender of the message or the recipient when you switch to the Sent or Drafts folder.
The position of the columns in list can also be adjusted by dragging the header of a specific column with the mouse and dropping it at where you’d like it to appear.
