Well, Outlook Express will only decrease the size of the folders once you pick "Shrink Folder" (or something similar), so it could be that the messages are deleted, but the folder size hasn't taken it into account yet.
(OK, it's: File->Folder->Compact)

Try what doyouwanthegreat says.

Also, make a copy of the folder files now (check the properties of each within Outlook Express to find their real locations) so that if something goes wrong, you might be able to use a 3rd-party tool to recover the data.
