I have a similar issue. I have gmail & att yahoo email accts. The email acct. that is on the phone with the envelope stopped working. I then installed the yahoo email, now i can't send a email with a attachment pic from my phone. I get the message sending failed. My phone keeps trying to send the email. I went into the phone email acct but was not able to set up the default acct., i get the message default acct. must be set. At times it asks from server setting, error 503. How do i resolve this?
