Why not just have an easy button that you can click saying Do Not Allow Reply All?
I know that there are some ways you can limit reply-all availability, like in the URL linked here. But there’s a note: If recipients open this email in other mail applications except Microsoft Outlook, such as opening on web page via web mailbox, they can reply all this email.
I’m semi-tech savvy but I’m no programmer. It feels like it should be easy to do, so either I’m totally wrong or email services are really missing out on a great thing they could do.
It was Oracle so they probably have a terrible internal email server that will have reply-all storm protection in a year or two.
I was working with the customer service software devs to migrate my team from Salesforce’s Desk.com (because Oracle hates Salesforce) and they said it would take 18 months to make a dropdown that you could type in and select a macro for a ticket. Eventually they gave up.
