I have an Exchange 2010, I have an user with its corresponding mailbox. This user has different mail addresses, and one of them is set in response address. I can receive the mails sent to any of the address, every time I try to send a mail the response address is added in the FOR, that is correct.
I have tried to sent mails using one of the no predeterminated mail address in the FROM field (directly typing) but when I open the recived mail I can only see the Response address.
My question is, can I use any of the other mail account in the FROM field?
