Email-saving files are pretty complicated. You would need to either find a component someone else has made that reads emails (like outlook :)), or write code to read the email yourself. That means handling the different message types (Rich Text, Plain Text, HTML), properly handling embedded data (pasted pictures, attachments, font color or face changes), and a whole host of similar issues.
This seems unjustifiably difficult, since there is OutLook already there. (There might be an easier way, but Iâm dubious.)
