One can create folders or service entries inside standard messaging folders like InBox or Drafts. The following code for creating subfolders does not result in the creation of a subfolder in older versions of S60 3rd Edition. However it works properly in S60 3rd Edition FP1.

Hearders Required:

#include <msvapi.h> 
#include <msvstd.h >

Library required:

LIBRARY   msgs.lib
