Introduction¶

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 emailaddress 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.

Hotmail SMTP OAUTH¶

If your account enabled two-factor authentication, you cannot login your account by normal user authentication, you shoulduse SMTP OAUTH or App Password.

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.

Microsoft will disable traditional user authentication in the future,switching to Microsoft OAuth (Modern Authentication) is strongly recommended now.

Or you can generate App Passwords and use this app password instead of your user password.

Send Email using Office 365¶

First of all, you should go to Office 365 “Outlook” -> “Options” -> “See AllOptions” -> “Account” -> “My Account” -> “Settings for POP, IMAP, and SMTPaccess”. You will get your Office 365 SMTP server address and port. Then you canuse your Office 365 SMTP server, port, user/password in the codes.

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