Hello friend!

This email should fail to be delivered at outlook.com because your server will not be an authorized sender for outlook.com. Microsoft will drop this and consider it a spoofed/spam sender. You can read more about SPF, the underlying function for this, here:

You will want the From email to always be from a domain that you can speak for, so that you can delegate the authority properly.
