Summary: With the "AnswerAll’ extension, users have the option to send a response to everyone who received a previously sent email. From the case history, users can also navigate to comments, and within the comment/reply interface, a selectable box is available to choose the recipients of the prior message.
Git, source code: We still have some work to do to polish the source code, we’ll post that when we’re done. If you need this plugin earlier, let us know and we’ll share the current state of the code.
If you have any questions regarding the extension, you can contact us: here.
