Errors 0x800CCC0D, 0x800CCC0E and 0x800CCC0FThe client connects to a port that is blocked or unavailable on the mail server. If you are attempting to send a message, the blocked port is 25 (SMTP), and if you are attempting to retrieve a message, the blocked port is 110 (POP3). Refer to the error message for the protocol and port numbers.
First check your Outlook settings, making sure that your POP3 and SMTP usernames, passwords and servers are correct. Also, make sure that your account and domain name are still active.
If the settings are correct and your account and domain name are active, one possibility is that you may not be connected to the Internet or the connection is bad. To test your connection follow the procedures below :
For incoming mail server (port 110)
- 1. Click the "Start" button then "Run". Type "telnet
2. Type in "USER" followed by your email address (example: USER info@hostaggio.com) and then press Enter. You should get a "+OK"
3. Type in "PASS" followed by your password (example: PASS secretpass) and press Enter. If it is correct, you will get another "+OK"
4. If you can do this, you have connected to the mail server, so the problem lies somewhere with your Outlook
If you get "-ERR authorization failed" at step 4, it is possible that your password has somehow become corrupted. Try changing it in your account's control panel and try again.
- 1. Click the "Start" button then "Run". Type "telnet
2. If you see "220 mail.somedomain.com ESMTP", you have connected to the mail server, so the problem lies somewhere with your Outlook
In the case you receive "connection refused" message or timeout, you need to contact your ISP with the request to open port 25 in their firewall (which they will probably not do). If they don't want to open the port you have to use their SMTP server for your outgoing mail connection. You can obtain their SMTP settings from either their tech support or possibly their web site.
The following service providers are currently known to block SMTP connections and require your use of their SMTP server: 1st.net, ATT WorldNet, Earthlink, Lineone.net, MSN, Mindspring, Sympatico, Bellsouth.
If you are running a firewall software, configure it to grant access to the Internet for the following file: Msimn.exe
If you have Norton Internet Security or Norton Personal Firewall read this and this information on Symantec's web site.
If you have the Norton Antivirus e-mail scanning feature enabled, read this information on Symantec's web site.
Error 0x800CCC79The cause of this error is due to the fact that the SMTP server requires authentication.

- 1. Click "Accounts" in the "Tools" menu
2. Click on your email account then click "Properties"
3. Click "Servers"
4. Make sure the "My server requires authentication" box is checked

2. Click on your email account then click "Properties"
3. Click "General"
