Outlook template to HTML

[TomasKochan1]

Hi, I have outlook template file (.oft) that users can update for the bot. We have to move from Outlook client API to Graph REST API. Is it possible to send email as JSON body having .oft mime type? If not, how could I convert .oft to HTML that'd preserve all formatting, indentation, line breaks etc?

Thank you

Tried example 4, where I converted .oft file to base64, however error states there is no recipient though template contains one.
