Been doing some playing around with the outlook.office.com webby app piece of shit I have to use for work.
There seems to be no way of actually replying inline or bottom posting you can do that will make it happy, it always just displays "(No message text)" in the message thread preview mode thingy - I have tried both from mutt and inside itself - then someone has to specifically click the message open to read it.
So basically shitty #outlook implementation is mandating top posting. Great.
