How to use the Outlook Object Library to send an email

.Net Office Interoperability Windows Forms

Sometimes we required to send email messages using Outlook Object Library instead of the conventional System.Net.Mail.SmtpClient class. While developing an desktop application, where I couldn’t hard code the SMTP server details and credentials. I found a solution using Outlook Object library, which will help to send email, with the current user context and credentials.

Here is the code snippet.

var application = new Outlook.Application();
var mailItem =
    application.CreateItem(Outlook.OlItemType.olMailItem) as Outlook.MailItem;
//Adding attachments.
    Add(@"C:\SampleAttachment.txt", DisplayName: "SampleAttachment");
//If email body contains some HTML formatting use this property.
//Instead use the Body property
mailItem.HTMLBody = "Hello World";
mailItem.Subject = "Subject";


Happy Coding
