How To Fix Error 0x8004210B In Outlook

Make sure all account settings are correct. One of the reasons for this error message is the wrong port number for the outgoing server (SMTP). For example, you set the port number to 465 (the port number for an encrypted connection) but forgot to check the SSL checkbox in Outlook 2002 and 2007, or set the Outlook dropdown menu to SSL, in which case you will receive error code 0x8004210B. If this is the cause of the problem, simply enable SSL encryption for port 465 in your email account settings, or use port 587 if you prefer to disable it.

Another similar issue that can cause this error in Outlook 2007 and Outlook 2010 is when you select TLS from the Outgoing Server Encryption (SMTP) drop-down menu and set the port number to 465. SSL / TLS Encryption Port Number actually 465, but what TLS means in Outlook 2007 and 2010 is actually STARTTLS. STARTTLS is not an encryption protocol, but a command to start TLS. Unlike SSL and TLS, STARTTLS works withfired ports. So if you chose TLS, set the outgoing server port number to 587 or leave the port number at 465, but change the encryption protocol to SSL from the drop-down menu.

Also make sure that the server names of the incoming and outgoing mail are correct and the same.

Your antivirus software can also trigger this error code. Temporarily disable your antivirus app and check your email account again to see if the problem persists. If you can send an email, then the anti-virus application is obviously the reason. Some antivirus programs allow you to disable scanning of outgoing (and incoming) email. Norton Internet Security / Norton Antivirus is known to cause this issue.
