We’re no longer able to provide access to Gmail emails through Xfinity Webmail. We’re working with Google to determine if we will be able to restore this capability, and we’ll contact you if we reach a solution. Please know your Gmail emails haven’t been affected. You can still sign into Gmail on your web browser and through the Gmail app to view your emails.
in your email settings disable/remove the gmail account you have linked within your comcast.net mailbox.
