Hi,
I have tested 3 different profiles IMAP, MAPI and ActiveSync and ActiveSync is not prompting for read receipt requests, while the other two are. The machine is using outlook 365, so is on the latest version of Outlook.

ActiveSync - read receipts
Re: ActiveSync - read receipts
Tried this on another outlook 2016 machine and an outlook 2013 machine and had the same problem, so seems to be more of an issue with ActiveSync. we are running 10.14 Premium.
