Listed below are common Outlook/Outlook Express error codes that may be returned when attempting to send, receive or access mail.

Error

Description

0x8004210A

The operation timed out waiting for a response from the receiving (POP) server. You should establish whether you can telnet to port 110 of your mail server.

0x800CCC0F

Your mail client is unable to contact your mail server, most likely because a firewall is preventing access or the supplied IP Address is incorrect, or that there is a problem with your internet connection.

0x8004210B

If you are experiencing this issue, verify that you have installed the service pack for Microsoft Office XP.

0x800CCC0D

If you are experiencing this issue, verify that you have configured your mail client correctly. You must either specify an IP address or a host name as the mail server when configuring the mail client settings. If you specify a host name then it must be defined in your DNS as a Host record.

0X800CCC0E

This error means that you are able to connect to the server via POP, but your SMTP Service is either not running or is configured incorrectly.

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