I believe there is nothing I can do about this behavior but I want to be thorough. The reason I ask is we will have had students send a Conversation message to multiple instructors and so they will all receive a notification to their email. One example we had is a student sent a message through Conversations to two different instructors who both received email notifications. Instructor A saw the email notification and responded to the student. This response did not go to Instructor B at all and Instructor B had no idea that the question had already been answered. It is a nice option to be able to respond directly from your email so it would be beneficial for us to have the ability to have everyone included in the Conversation to be notified about this response.
