Office365 in Javascript from Windows Store Apps - HTML5 - UWP¶

In previous section, I introduced how to send email using Yahoo account. In this section, I will introduce how to use your Hotmail/MSN Live/Outlook.com/Office365 account to send email in JavaScript.

Sections:

Introduction
[JavaScript - Send email using Hotmail/MSN Live/Outlook.com account over TLS connection]
Hotmail SMTP OAUTH
Send Email using Office 365
App Password and SmtpClientAuthenticationDisabled
[JavaScript - Send email using Office365 account over TLS connection]
Office365 EWS OAUTH

Introduction¶

Hotmail/MSN Live/Outlook.com SMTP server address is smtp.office365.com. It requires TLS connection to do user authentication, and you should use your Hotmail/MSN Live/Outlook.com email address as the user name for ESMTP authentication. For example: your email is liveid@hotmail.com, and then the user name should be liveid@hotmail.com.

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

        // Set email body
        oMail.textBody = "this is a test email sent from Windows Store App using Hotmail.";

        // Hotmail SMTP server address
        var oServer = new EASendMail.SmtpServer("smtp.office365.com");

        // User and password for Hotmail authentication
        oServer.user = "livid@hotmail.com";

            // Display Result by Diaglog box
            (new Windows.UI.Popups.MessageDialog(result, "Success")).showAsync();
            btn.disabled = false;
        },

        function (e) {
            // because javascript exception only gives the stack trace messages, but it is not
            // real description of exception, so we give a property lastErrorMessage for javascript.
            if (oSmtp.lastErrorMessage != "") {
                result = oSmtp.lastErrorMessage;
            }
            else {
                result = e.message;
            }
            oSmtp.close();

            // Display Result by Diaglog box
            (new Windows.UI.Popups.MessageDialog(result, "Error Information")).showAsync();
            btn.disabled = false;
        });
    }
})();

Hotmail SMTP OAUTH¶

If your account enabled two-factor authentication, you cannot login your account by normal user authentication, you should use 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. This way is more secure, but a little bit complex.

Using Microsoft Hotmail SMTP OAUTH

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

Send Email using Office 365¶

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

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

App Password and SmtpClientAuthenticationDisabled¶

If your account enabled two-factor authentication, you cannot login your account by normal user authentication, you should create an App Passwords and use this App Password instead of the user password.

You should also check if authenticated client SMTP submission (SMTP AUTH) is enabled:

Enable or disable authenticated client SMTP submission (SMTP AUTH) in Exchange Online.

Last update: Microsoft has disabled App password, you have to switch to Hotmail SMTP OAUTH and `Office365 SMTP/EWS/Ms Graph API OAUTH`_. If you don’t want to change your code, you can have a try with EA Oauth Service.

[JavaScript - Send email using Office365 account over TLS connection]¶

The following example codes demonstrate how to use EASendMail SMTP component to send email using Office365 account. To get the full samples of EASendMail, please refer to Samples section.

(function () {
    "use strict";
    var appViewState = Windows.UI.ViewManagement.ApplicationViewState;
    var ui = WinJS.UI;
    var htmlinited = false;
    var editor;
    var asynCancel = null;
    var m_atts = new Array();
    ui.Pages.define("/default.html", {
        // This function is called whenever a user navigates to this page. It
        // populates the page elements with the app's data.
        ready: function (element, options) {
            init_gui();
        },

        unload: function () {

        }

    });

    function init_gui() {

        // add OnClick event handler
        var btn = document.getElementById("btnSend");
        btn.addEventListener("click", send_email, false);
    }

    function send_email() {
        var result = "";

        var oMail = new EASendMail.SmtpMail("TryIt");

        // Set office365 sender email address, please change it to yours
        oMail.from = new EASendMail.MailAddress("myid@mydomain");

        // Add recipient email address, please change it to yours
        oMail.to.add(new EASendMail.MailAddress("support@emailarchitect.net"));

        // Set email subject
        oMail.subject = "test email from JavaScript HTML5 project";

        // Set email body
        oMail.textBody = "this is a test email sent from Windows Store App using office365.";

        // Office365 SMTP server address
        var oServer = new EASendMail.SmtpServer("smtp.office365.com");

        // User and password for office365 authentication
        oServer.user = "myid@mydomain";

        // If you got authentication error, try to create an app password instead of your user password.

        oServer.password = "your password or app password";

        // Enable TLS connection on 587 port
        oServer.port = 587;
        oServer.connectType = EASendMail.SmtpConnectType.connectSSLAuto;

        var oSmtp = new EASendMail.SmtpClient();

        var btn = document.getElementById("btnSend");
        btn.disabled = true;
        oSmtp.sendMailAsync(oServer, oMail).then(function (e) {
            result = "Email was sent successfully!";

            // Display Result by Diaglog box
            (new Windows.UI.Popups.MessageDialog(result, "Success")).showAsync();
            btn.disabled = false;
        },

        function (e) {
            // because javascript exception only gives the stack trace messages, but it is not
            // real description of exception, so we give a property lastErrorMessage for javascript.
            if (oSmtp.lastErrorMessage != "") {
                result = oSmtp.lastErrorMessage;
            }
            else {
                result = e.message;
            }
            oSmtp.close();

            // Display Result by Diaglog box
            (new Windows.UI.Popups.MessageDialog(result, "Error Information")).showAsync();
            btn.disabled = false;
        });
    }
})();

Office365 EWS OAUTH¶

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

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.

Using Microsoft Office365 EWS OAUTH

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