@at_theresonly1mac you are obviously composing an email, which mtv11 already mentions works. There is no From field for replies or forwarding mail. I am also extremely annoyed by this and especially that everytime I have a problem I see unresolved issues with no useful replies. Someone else will read my reply and think the same. I will just skip Samsung and use gmail straight, there it works.
Ps ... Next time you send me a ***** reply, I will report you. I give my answers for free, I am not a moderator... It will say next to my name if I was.
