Creates a reply email in the Drafts folder, updates the reply with information, and then sends the reply.

Note: This example requires Chilkat v9.5.0.68 or greater.

This example applies to: Exchange Online | Office 365 | Hotmail.com | Live.com | MSN.com | Outlook.com | Passport.com

    // First we need to get the folder ID for /Inbox.
