Send email via X++ code in Dynamics 365 F&O

  1. First step on How to send email via x++ code D365 FO, we will create a class and a static method in it as shown below
/// <summary>
/// Send mails
/// </summary>
class LSSendingMail
{
    /// <summary>
    /// Send EMail
    /// </summary>
    /// <param name = "_toEmailid">_toEmailid</param>
    /// <param name = "_template">_template</param>
    /// <param name = "_placeHolderMap">_placeHolderMap</param>
    public static void sendMail(LSEmailAddress _toEmailid, SysEmailSystemId _template , Map _placeHolderMap)
    {
        #define.language('en-us')
        SysOutgoingEmailTable   outGoingEmailTable;
        SysEmailSystemTable SysEmailSystemTable = SysEmailSystemTable::find(_template);
        SysEmailMessageSystemTable SysEmailMessageSystemTable = SysEmailMessageSystemTable::find(_template,#language);

        str messageBody = SysEmailMessageSystemTable.Mail;
        str subject = SysEmailMessageSystemTable.Subject;
      
        messageBody = SysEmailMessage::stringExpand(messageBody, _placeholderMap);
        subject     = SysEmailMessage::stringExpand(subject, _placeholderMap);
        
        outgoingEmailTable.EmailItemId                  = EventInbox::nextEventId();
        outgoingEmailTable.TemplateId                   = _template;
        outgoingEmailTable.Sender                       = SysEmailSystemTable.SenderAddr;
        outgoingEmailTable.SenderName                   = SysEmailSystemTable.SenderName;
        outgoingEmailTable.Recipient                    = _toemailid;
        outgoingEmailTable.Subject                      = subject;
        outgoingEmailTable.Message                      = messageBody;
        outgoingEmailTable.Priority                     = SysEmailSystemTable.Priority;
        outgoingEmailTable.WithRetries                  = true;
        outgoingEmailTable.RetryNum                     = 0;
        outgoingEmailTable.UserId                       = curuserid();
        outgoingEmailTable.Status                       = SysEmailStatus::Unsent;
        outgoingEmailTable.LatestStatusChangeDateTime   = DateTimeUtil::getSystemDateTime();
        outgoingEmailTable.insert();

    }

    /// <summary>
    /// Send email attachment
    /// </summary>
    /// <param name = "_toEmailid">_toEmailid</param>
    /// <param name = "_template">_template</param>
    /// <param name = "_placeHolderMap">_placeHolderMap</param>
    /// <param name = "docuRef">docuRef</param>
    /// <param name = "_fileType">_fileType</param>
    /// <returns>boolean</returns>
    public static boolean sendMailwithAttachment(LSEmailAddress _toEmailid, SysEmailSystemId _template , Map _placeHolderMap,DocuRef docuRef, Str _fileType = 'application/pdf')
    {
        boolean messageSent;
        #define.SMTP('SMTP')
        Map sysMailers = SysMailerFactory::getMailers();
        SysEmailSystemTable SysEmailSystemTable = SysEmailSystemTable::find(_template);
        SysEmailMessageSystemTable SysEmailMessageSystemTable = SysEmailMessageSystemTable::find(_template,SysEmailSystemTable.DefaultLanguage);

        str messageBody = SysEmailMessageSystemTable.Mail;
        str subject     = SysEmailMessageSystemTable.Subject;

        var messageBuilder = new SysMailerMessageBuilder();

        messageBuilder.addTo(_toEmailid);
        messageBuilder.setSubject(SysEmailMessage::stringExpand(subject, _placeholderMap));
        messageBuilder.setBody(SysEmailMessage::stringExpand(messageBody, _placeholderMap));
        messageBuilder.setFrom(SysEmailSystemTable.SenderAddr);

        //var message = messageBuilder.getMessage();

        messageBuilder.addAttachment(DocumentManagement ::getAttachmentStream(docuRef),docuRef.Name + '.pdf',_fileType);
        SysIMailer mailer;
        mailer = sysMailers.lookup(#SMTP);

        SysIMailerNonInteractive nonInteractiveMailer = mailer;
        messageSent = nonInteractiveMailer.sendNonInteractive(messageBuilder.getMessage());

        return messageSent;
    
    }

}

2. Now to show you the example of how to send email via x++ code D365 FO, we will create a runnable class

internal final class TestAY
{
    /// <summary>
    /// Class entry point. The system will call this method when a designated menu 
    /// is selected when execution starts and this class is set as the startup class.
    /// </summary>
    /// <param name = "_args">The specified arguments.</param>
    public static void main(Args _args)
    {
        #define.User('User')

        Map placeHolderMap = new Map(Types::String, Types::String);
        placeHolderMap.insert(#User, "Atul");
        LSSendingMail::sendMail('atul.yadav@lifestyles.com', 'Safety Cal', placeHolderMap);
    }
}

3. Now for 3rd step on How to send email via X++ code D365 FO, for the above code to run you need to set up an email template named “Safety Cal”

a. Go to System email templates

System email templates
System email templates

b. You will see a form below

system email template form
System email template form

c. Now click on new and create a new template as shown below

New system email template
New system email template

d. I am filling as below

New system email template data
New system email template data

e. Once created click on the email message as shown below

Email Message
Email Message

f. once you click, you will see a new form like below

Message template
Message template

g. Here we need to upload the HTML format of our email, I have already attached mine

My HTML sample below

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Safety Calendar Reminder</title>
</head>
<body>
    <p>Dear %user%,</p>
    <br>
    <p>A gentle reminder to promptly complete your Safety Calendar entries, due by the end of this week. Your timely contribution is vital for our collective safety and compliance.</p>
    <p>For assistance or queries, please contact us.</p>
    <br>
    <p>Best regards,</p>
    <p>Microsoft Dynamics 365</p>
</body>
</html>

4. Now for the last step on How to send email via X++ code D365 FO, you need to run an Email distributor batch, the path shown below

Email distribution batch
Email distribution batch

Now just run the runnable class that we created in Step 2
