And then there was IRM which allowed an e-mail sender to restrict a recipient from reply-all functionality.
Very Useful when sending an e-mail to a large amount of people.
(I will not discuss pain points here. )
But how about preventing a reply-all without IRM ?
Oh yes its possible, and no this is not some new feature of outlook 2010. It existed even before IRM was on the scene.
First a brief line on forms...
In the outlook world, Every e-mail, calendar entry, contact, task, note is a form.
You can create your own form put icons on it, write code behind the icons to react to user actions.
When you send an e-mail you are using the IPM.Note form.
So the next time you want to prevent a reply-all how about just removing or disabling the code behind the reply-all ?
Now to prevent a reply all just remove the functionality behind the icon.
That is exactly what the procedure documented in the below link does.
Warning : this is not a true reply-all prevention solution. It just turns off the reply all icon in outlook.
