(VB.NET UWP/WinRT) Send Email with Hotmail (live.com) -- smtp-mail.outlook.com

Demonstrates the SMTP settings required for sending email through Hotmail (A live.com email address). The Hotmail SMTP server is smtp-mail.outlook.com and receives connections on the SMTP port 587. It expects STARTTLS to establish an explicit TLS connection.

Note: When I first tested this code, I received the following error:

550 5.3.4 554-554 5.2.0 STOREDRV.Deliver; delivery result banner

Mozilla Thunderbird also encountered the same error. I then started a browser, visited outlook.live.com, and logged in to my account. I probably hadn't done that for a very long time. I then retried running this example, and everything worked.

Also, it seems that the SMTP server hostname can be either "smtp-mail.outlook.com" or "smtp.live.com". Both worked.
