Recently installed Outlook 2010, it properly sent and received email from ATT account. Subsequent efforts to receive email from my ATT account fail to receive the messages. The error message is 0x80040154. I verified the pop and smtp server settings and profile setting with an ATT rep and also reset the servers settings inthe Outlook profile. Everything matches but still no email. I am using Kaspersky anti virus, the windows firewall, and Windows XP sp3. Any ideas?
