The helpdesk is frequently receiving calls regarding the proper settings for sbcglobal.net Outlook settings and att.net Outlook settings. If your email account is still pointing to the pop.sbcglobal.yahoo.com and smtp.sbcglobal.yahoo.com servers, you are likely receiving a certificate warning issue when sending and receiving mail. AT&T changed these severs over a year ago.
