I have been unsuccessful in setting up a second email on Outlook 2011 for my wife to use. She has an Xfinity username and email address and I am able to send email to her email address. But, when I try to send myself an email from her address or reply to mine that I sent her it dosen't work. Further, when I type in her email address in the "To" space my name shows up as the name rather than hers. Help!
Did you configure the account manually in Outlook? Or will it auto-configure it for you after inputting the user ID and password? Are you getting any error message when trying to send from that account in Outlook?
