Generate .MSG file from Receive Message Event Node

Hi Everyone,

Is there any way or smart service to generate the .MSG file whenever receive an email to Appian . We know, there is smart service eml and msg conversation plugin but would like to do it in one step and don't want to dependent on the too many third-party plugins. Also once generated the .MSG ,need to read and  display in the UI screen . Please let mw know, Any implementation around it.

Thanks!!
