// This example requires the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

Chilkat.Http http = new Chilkat.Http();

// Use your previously obtained access token here:

// This example will create a new mail folder as a child of /Inbox/abc

// Get the existing folder ID from the folder map created by this example
