How to determine the folder of a message found by Search

For a message found by Searching, how can you determine the folder in which it was found?

You will need to display the folder column. In the default compact layout that is difficult to do because there are only 3 columns displayed; from, subject and date. You can change them, but you will still only have 3.

If you change the layout to a single line layout, you can add more columns. To get the single line layout, drag the right border of the message list to increase the width to more than 600 pixels, or change the setting in Menu > Tools > Settings > Mail > Read > Message List

Brilliant - thank you!
