[C++] [MAPI] How to force mail sendind ?

My question is how, in the soft, flush an outlook account.
I can create a email "ready to be send" but if i want it to be send immediatly how i do ?

1- Create an email :i know how to do that
2- Send the email :i don't know as my email is marked "ready to be send" i want to send immediatly without user intervention
