I am getting multiple e-mails with a random person's name as the sender and someone from my address book as the subject. I have changed by password but am still getting the e-mails. What can I do to sop this?
Mark them as spam. https://www.xfinity.com/support/articles/mark-email-as-spam-xfinity-connect
The spammer/scammer may not have gotten into YOUR address book – they may have gotten into a friend's address book which has many of the same contacts. Once they have someone's address book, the data is out there and there's not much to be done about it. (Unless the people whose email addresses are being used are willing to switch to new addresses.)
