Outlook: Error Message: A Connection Failure Has Occurred (Error -23012)
When you try to send and receive messages by using Outlook Express, you are able to send messages, but you may receive the following error message when incoming messages are delivered:
Could not retrieve mail from the account A connection failure has occurred (error -23012).
This behavior can occur because of a failed response to the Authenticated Post Office Protocol (APOP) request from Outlook Express to the Post Office Protocol version 3 (POP3) server. The failure occurs because the server is not responding in a manner that is consistent with accepted standards.
To resolve this behavior, check your internet connection. Try a reboot, if it still occurs contact us.
