The error 0x800CCC79 in Outlook Express is primarily an SMTP authentication error which emerges in Outlook Express when users try and attempt to send/receive emails. This occurs due to the improper or no authentication of the user’s email and hence the outgoing SMTP server denies accepting user’s e-mail before sending any emails. And in that situation, the messages which users send can’t be sent because the receiver’s SMTP server denies accepting the email. That declined e-mail address will appear as ‘firstname.lastname@example.org’ and hence the subject is shown as Subject ‘Re: Test’ your account. However, users need to contact the technical experts to solve this problem as it is a bit tricky and they will need the expert’s hand to solve this problem. So, reach them through outlook customer service number.
