(SQL Server) Insert Email into GMail Folder

Directly inserts a message into only this user's mailbox similar to IMAP APPEND, bypassing most scanning and classification. Does not send a message.

This example will create a Chilkat Email object and upload/insert it into GMail. Then adds the "INBOX" label to the email to make it appear in INBOX

Note: This example requires Chilkat v11.0.0 or greater.
