How to open the new Outlook to send en email with attachments?

Question

Hello,

I would like to know how to open the new Outlook mail to send an email with attachments in c#.

I tried generating an .eml file and open it in the new outlook but the new Outlook does not support the X-Unsent: 1 flag. So the email does open, but you cannot send it.

Thanks

Hi @Wambo ,

You can use Microsoft.Office.Interop.Outlook Namespace.

Check the following code.

using Outlook = Microsoft.Office.Interop.Outlook;

            Outlook.Application outlookApp = new Outlook.Application();

            Outlook.MailItem mailItem = (Outlook.MailItem)outlookApp.CreateItem(Outlook.OlItemType.olMailItem);

            mailItem.To = "recipient@example.com";

            mailItem.Subject = "Test Email";

            mailItem.Body = "This is a test email.";

            mailItem.Attachments.Add(@"C:\Path\To\File1.txt");

            mailItem.Send();

Best Regards.
