AT&T - Receiving reported error 0x800CCC0F - Connection to the server interrupted.
AT&T emails (@sbcglobal.net) sent to me are not being delivered to Outlook 365 or Thunderbird. Total stoppage of email delivery for past 24 hours. Received emails appear in webmail. Other email addresses are being received. Issue with receiving AT&T emails has been an ongoing issue for past several years. Email setup includes secure mail key. Using mail.yahoo.com for server.
What's the fix for this?
