My iMac (macOS Monterey 12.6.6) runs Mail.app 16.0. Mail.app has a number of subfolders within a user-created folder called "Old Trips.” Each subfolder contains emails relating to a specific journey.
I would like to sort these subfolders so the subfolders list in the order of their creation, that is, with the most recent trips on top and the oldest trip at the bottom. A friend suggested renaming each of the subfolders with a unique starts-with-a-number name. I tried that, but even after quit and macOS restart no sorting occurred.
Is there another way to accomplish this sort?
