Is it possible to send an e-mail with attachment in Office 365? As attachment we would want the attachment from a list item or local system or a document from a document library.

I tried using a SMTP server in a custom webpart (which failed because SMTP isn't allowed)

Is this solution possible?

I had written below code for send by mail.

$(document).on('click',"button[data-automation-id='sendByEmailDialogSendButton']", function (event) {
    loadScript("https://smtpjs.com/v3/smtp.js", function(){
            SecureToken: "35c2dcb7-b282-47ce-b894-4fe52a3f071a",
            Host : "smtp.gmail.com",
            EnableSsl :false,
            Username : "Gmail Username",
            Password : "password",
            To : 'SharePOint Id([email protected])',
            From : "Gmail Id([email protected])",
            Subject : "Send by admin",
            Body : "And this is the body"}).then( message => alert(message));

Throwing error “The SMTP server requires a secure connection or the client was not authenticated. The server response was: 5.7.0 Authentication Required.”

To send email from SharePoint, using JavaScript, then you can use SP.Utilities.EmailProperties object (sp.js), it has the following properties,

From, To, CC, BCC, Subject, Body , 

it doesn't have any property for attachments

As an alternate, you can upload the document into a library and send the link over emails.

For more information, refer the below links,
