I am trying to respond to a large amount of emails. Home come I canot select more than one email to respond to. The Reply button goes GREY. Why is that?
Because you can't reply to more than one email at a time using the Reply
button. Oh, wait, you said that already. Oops. What you can do is add
the sender to your Contacts list, create a group (distribution list),
and send the reply to that group.
