How to stop accidentally closing outlook in outlook 2016

Is there a way of stopping you accidentally closing down outlook in Outlook 2016 please? I tend to have a few emails open when i accidentally close outlook itself rather than an outlook message. It's very very annoying. Is there a way of stopping this please?

There is a free Quick Tweaks add-in that provides this option: "Minimize Outlook on close".

Sounds like there's nothing out of the box without a third party app.
