I can no longer delete email from my outlook express program.  I have it programmed to delete all items from the delete folder when I shut the program, and I now get an error message.  It says "Some of the items in the deleted items  folder could not be deleted.  An error has occurred. "  There is no error number, and none of the items are deleted.  I also cannot delete the items manually.  Does anyone have an answer to this problem, or have they ever encountered it?
