The following vb 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
and then the user name should be
Office 365 SMTP Server
Office 365 SMTP server uses 587 port and explicit SSL (TLS) connection.
|smtp.office365.com||25, 587 (recommended)||TLS|

Microsoft Live SMTP servers (Hotmail, Oultook personal account) have been extended to support authorization via the industry-standard OAuth 2.0 protocol. Using OAUTH protocol, user can do authentication by Microsoft Web OAuth instead of inputting user and password directly in application. This way is more secure, but a little bit complex.
Microsoft Office365 EWS servers have been extended to support authorization via the industry-standard OAuth 2.0 protocol. Using OAUTH protocol, user can do authentication by Microsoft Web OAuth instead of inputting user and password directly in application. This way is more secure, but a little bit complex.
Seperate builds of run-time dll for 32 and x64 platform
