Aspose.Email Product Family

Hi Team.

I am creating the .msg file using the Aspose.Email library. A sample file is attached to this email.

I encountered the error message below while attempting to send this email file. Could you please look into this issue?

If we can successfully send the email using the new Outlook version, we are planning to purchase the Aspose.Email license.

Note: We can send emails using a different version of Outlook.

Hello @ashokdar15 ,

Yes, our developers have investigated the issue and came to the following conclusion:

It seems that the new version of Outlook doesn’t allow sending emails in the MSG format.
You can check it for yourself:

  • create an email in the old Outlook
  • save it in MSG format
  • open the saved MSG file in the new Outlook, and try to send the email

The result will be the same. Only EML files can be successfully sent in the new Outlook.

You can save the message in EML format to send it with the new Outlook.

I created the EML file using the above code.
But when I open it in the new Outlook body in the mail is missing.

@ashokdar15,

Using the HtmlBody property and wrapping the content with the proper HTML structure (<html><body></body></html>) ensures that the email is correctly formatted as HTML. Here’s the corrected example for setting up the email message body in Aspose.Email:

var message = new MailMessage
{
    Subject = "Test Subject",
    IsBodyHtml = true,
    HtmlBody = @"<html><body>Dear Customer, <br/><br/>We are pleased to inform you that your request has been processed successfully. 
Please find the attached document for further details regarding the quote. 
As a reminder, we ensure that all customer requests are handled with utmost priority. 
If you have any additional questions or concerns, feel free to reach out to our customer service 
at your earliest convenience.<br/><br/>This is an automated message, please do not reply. For any queries, kindly
 contact us at support@mtnl.com.<br/><br/>Best Regards,<br/>MTNL Support Team<br/><br/>
Note: The attached file contains sensitive information. Please review the document carefully and keep it 
safe for future reference.<br/><br/>Important: Make sure to verify the details mentioned in the document to avoid 
any discrepancies later. Thank you for choosing our service and trusting us with your requirements.<br/><br/>We 
look forward to serving you better in the future!</body></html>"
};

Using HtmlBody and setting IsBodyHtml = true, will ensure the email content is processed and displayed as proper HTML.
