Managed C++/CLI - Send Email using Hotmail, Outlook.com, Office 365

The following C++/CLI example codes demonstrate how to send email using Hotmail, Outlook.com and Office 365 SMTP servers.

Hotmail, Outlook.com SMTP Server

Hotmail/Live/Outlook.com SMTP server address is smtp.live.com. It requires explicit SSL (TLS) connection to do user authentication, and you should use your Hotmail/Live/Outlook.com email address as the user name for ESMTP authentication. For example: your email is myid@hotmail.com, and then the user name should be myid@hotmail.com.

Server Port SSL/TLS
smtp.live.com 25, 587 TLS

Office 365 SMTP Server

Office 365 SMTP server uses 587 port and explicit SSL (TLS) connection.

Server Port SSL/TLS
smtp.office365.com 25, 587 (recommended) TLS
