I am running Outlook Mac v 16.52 (checked in 'about outlook')
When I reply to a message the header of that message is often not shown, just the message text
and there's not even a line to separate that from my reply (though original text is indented)
Sometimes it works OK
e.g. if I hit 'reply' to an Amazon order confirmation the header details are there.
It's very strange but I really wish Microsoft could figure out and fix it !
