Specify Outlook Font For Plain Text Emails

I get various reports by email but Outlook, by default, uses a proportional font to display them, resulting in "crooked columns".  But since just these reports come in as "plain text", I found I can change Outlook to use a non-proportional font, Courier New in the example below, to straighten up the reports and make them much more readable.
