really need help on this complicated issue. I have 2 exchange accounts set-up on my iPhone5. 1. johndoe@abc-company. - this account receives e-mail from this address and also receives forwarded e-mail from the 2nd account(below) 2. sales@NEWcompany - this account does not actually receive any mail in the in box, it is set up as a group distribution to others in the NEWcompany. on iPhone, I have enabled view of combined 2 inboxes. my default account is johndoe@abc-company. but when i receive in an e-mail which i know was sent to the "sales@NEWcompany", i would like to reply, and change the "FROM" as coming from NEWcompany address. I am able to do this in outlook for mac 2011 (and was also able to do this in outlook on PC), but would like to do same from my iPhone.
