Using Classic Outlook on Windows for personal email, calendar, and contact management
Thanks, but setting a message option when sending a message, is not acceptable. Our users use Outlook for the vast majority of their message needs, but may check OWA for a delivery report after hours. Also, just requesting a delivery report does not provide the info on whether it was read, or not. The user must also select "Request a Read Receipt", which if the recipient selects "No", then the sender still has no idea if it was read, or not.
Why would Microsoft remove this function in the current version of OWA? I will provide feedback at the link you provided, but experience tells me not to hold my breath.
