Send Mhtml email in C# using Chilkat - LoadEml()

Question

Hello there,

I have a requirement to send emails containing both text and Images.
So, I have .mhtml file that contains the content that needs to be emailed over and
I am using Chilkat for that.

        success = objEmail.LoadEml(@"C:\Test.mhtml");
        objEmail.Subject = "Test Mhtml";
        objEmail.From = "[email protected]";
        objEmail.AddTo("Test", "[email protected]");
        objEmail.AddCC("Test", "[email protected]");
        success = objMailMan.SendEmail(objEmail);

I am facing one issue here-
When I send the same email to my gmail account, it is sent as required i.e display mhtml file content as email body(text + images).

But, when I receive same email in my office outlook, instead of showing as email body, I get different attachments(html, image files).

Is there some setting in my outlook that forcing so?

Any clue?
