CAUSE
You may receive these error messages if one of the following conditions is true:
 * An incorrect server name is used for the POP3 server or for the SMTP server.
 * The server computer is unavailable or is unreachable.

Note Besides the error messages that are mentioned in the &quot;Symptoms&quot; section, the following error numbers have been reported:
 * 23012
 * 5553
 * 5551

To resolve any one of these errors, verify that the account settings for the POP3 server or the SMTP server are correct



Troubleshooting
 Verify with your network administrator or Internet service provider (ISP) that you are using the correct mailbox name and the correct server IP address. Verify that the Entourage client can connect to the POP3 server or to the SMTP server. To test the connection, use one of the following methods:  Ping the server by using the name that was provided to you by your ISP or by your network administrator. The Ping utility is located in the Utilities folder. Telnet to the default POP3 port or to the SMTP port.  In the Utilities folder, double-click the Terminal program.</li> At the Terminal prompt, type the following to test for SMTP connectivity: >>Telnet < > 25

Note  is a placeholder for the name of your SMTP server.</li></ol>

If the connection is successful, you will see text that is similar to the following:

+OK Microsoft Exchange Server 2003 POP3 Server Version 6.5.7226.0 (Server.contoso.net) ready.

If the connection fails, this may indicate a problem with the mail server, or it may indicate that the SMTP port is blocked.</li></ul> </li></ul>
