Gets or sets which HTML-to-RTF conversion method to use when making .MSG out of .EML source.
The default value is Internal which means MailBee's own HTML-to-RTF converter will be used during .EML into .MSG conversion.
Because MailBee's internal converter cannot transform all the HTML formatting into RTF formatting (this would be an extremely complex task because both formats have lots of formatting mechanisms and they are very different), you can also not use the conversion at all (None) because modern Outlook versions can read .MSG with HTML and no RTF just fine. Also, if you strictly need RTF and MailBee's converter is not suitable for you, you can plug your own converter in (for instance, if you have a dedicated component for HTML-to-RTF conversion). See HtmlToRtfConversionMethod topic for details.
