I have two Exchange accounts that I need to keep separate. I cannot figure out how to get iOS to not send ALL outbound emails through one of the accounts. If I'm in Exchange account "A", I want outbound emails to go out through A... if in B, then B. This used to work fine but now all outbound email goes through account A. In the email, I can set the account, but regardless of the account I choose, it always goes out from account "A". Any thoughts on how to solve?
