In the Resource Navigator, right-click the message set folder that
you are deleting, then click Delete on the pop-up menu. This opens the Confirm Resource Delete window,
which asks whether you want to delete the resource that you have specified.
Click Yes to delete the message set or No to
cancel the message set deletion. Pressing the Esc key on your keyboard also
cancels the message set deletion.
Important: When you delete a message set, the action can
not be undone once you have confirmed the deletion. All folders and associated
files for the message set are deleted.
