I intended to delete a subfolder, and would swear in a court of law that is the choice I made in the UI.

However, the parent folder and all its subfolders were deleted thereby wrecking my entire mail management system (macros, etc.). It will take me many hours to rebuild this, and many of the de-foldered mails were action items.

There should also be the option to Undo the deletion, given the catastrophe described above.

Thank you
