Downloaded e-mails are no longer marked as read on att.net
Beginning Feb. 1, 2017, emails that are downloaded from att.net to an email client (program) are no longer being marked as read. I use Thunderbird, and my wife uses Outlook 2010. Both our accounts are set up as POP3. Prior to Feb. 1, 2017, after an email was downloaded by either Thunderbird or Outlook, the email showed as read on att.net. What changed on 2/1/2017?
