What do you mean no account?

em client will not let me forward an email, telling me there is no account from which to send the email. But it gets my emails, so obviously there is an account set up. How do I fix this?

Hi, sending and receiving emails is not same thing.

can you go to Tools - Accounts - your account and tell me what tabs do you see? Also tell me your email account provider so I can provide better help.
