Re: Exchange is featureless?
In what way? I think most servers are capable of cancelling a reply all automatically, and the article confirms that was possible in this case as well. That doesn't help if someone doesn't enable it for the message, though. So does your server manage to automatically determine that this is necessary? Does it also work correctly when someone is supposed to reply all to a message with a lot of recipients, for example to update its content? That happens too.
