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

Dim http As New Chilkat.Http

// This example will search /Inbox for a message we want to delete.
// First we need to get the folder ID for /Inbox.
// Then we'll search for messages based on some criteria, and delete the matching messages.

// Get the folder ID for /Inbox from the folder map created by this example
