Coming from https://stackoverflow.com/questions/68318423/how-to-change-coercion-type-of-email-body-to-html-from-text-using-outlook-add-in. There, it is linked to this community, to request the feature.
I want to add functionality to my Add-in for changing the bodyType to HTML. Unfortunately, that doesn't seem to be supported right now, at least not when the question on stackoverflow was posted.
