Error

Service

Description

0x800CCCF4

HTTPMail

Outlook settings may be invalid or a firewall is preventing connection to the remote MailEnable Server.

0x800CCC79

SMTP

SMTP Relay settings are preventing the sending of messages to MailEnable. Ensure that SMTP Authentication is enabled.

0x80042109

SMTP

Outlook is unable to connect to the outgoing (SMTP) e-mail server.

0x8004210A

POP

The operation timed out waiting for a response from the receiving (POP) server. Establish whether it is possible to telnet to port 110 of the mail server.

0x800CCC0F

POP

The mail client is unable to contact the MailEnable Server, most likely because a firewall is preventing access or the supplied IP Address is incorrect.

0x8004210B

POP

Verify that the service pack for Microsoft Office XP is installed.

0x800CCC0D

POP

Verify that the mail client is configured correctly. Either specify an IP address or a host name as the mail server when configuring the mail client settings. If using a host name then it must be defined in the DNS as a Host record.

0X800CCC0E

SMTP

This error means that the mail client is connecting to the server via POP, but the SMTP Service is either not running or is configured incorrectly.

Verify if the SMTP service is running by using the telnet utility to telnet to port 25 of the mail server. If the server responds, then the issue is most likely that mail client settings are invalid.
