The message could not be sent because the server rejected the sender's e-mail address. The sender's e-mail address was 'marcparadis1@comcast.net'. Subject '', Account: 'POP3', Server: 'smtp.comcast.net', Protocol: SMTP, Server Response: '550 5.1.0 Authentication required', Port: 587, Secure(SSL): No, Server Error: 550, Error Number: 0x800CCC78

If using port 587, please ensure that you configure your POP client in Outlook Express for "My Outgoing mail server (SMTP) requires authentication"

comcast recently changed some of the ports for various customers, you may need to enter your password at least once after you change the port.

These are some codes. may be these will help some.

0x800CCC00 LOAD SICILY FAILED - Authentication did not load.

1. Try closing and restarting Outlook express
2. If still getting same error, wait 20-30 minutes for a server reset of your account then try again
3. It could be a corruption of the user account in Outlook Express. Try setting up a second identity and see if it works

0x800CCC01 INVALID CERTIFICATE CONTENT

1. Get your certificate re-issued by your authority server

0x800CCC02 INVALID CERTIFICATE DATE

1. Get your certificate re-issued by your authority server

0x800CCC03 USER ALREADY CONNECTED

1. You may be logged in on another machine. Close all connections on all machines, wait 20-30 minutes and try again
2. Some mail servers will not recognise an improper disconnection. This will result in the account being 'Poplocked'. Either wait 20-30 minutes for it to time out or get somebody to shell into the mail server and stop the mail task that is running on the account. This can normally only be done with accounts that have UNIX shells
3. If you are not logged in on another machine or poplocked then someone may be using/downloading from your account or something is wrong with your account

0x800CCC04 CONN

0x800CCC05 NOT CONNECTED TO SERVER

1. Can you get web pages? If so, you may have the wrong mail server typed in your account settings or the server may be down
2. If you cannot get web pages then hang up and try connecting again
3. Reboot the computer and try again
4. If it's still not working and you are not getting any web pages, then data may not be moving across the network properly. Check DNS numbers, remove and then reinstall TCP/IP in Control Panel > Network.

0x800CCC06 CONN SEND

0x800CCC07 WOULD BLOCK

0x800CCC08 INVALID STATE

0x800CCC09 CONN RECV

0x800CCC0A MESSAGE DOWNLOAD INCOMPLETE

1. This is a possible corruption of the pop3uidl file. Close the Internet connection and all programs. Search for the file 'pop3uidl and delete it. Reconnect and it should work
2. Repeat step 1 with a reboot before you check your mail again
3. You may have a corrupt or a very large file attachment on the mail server. Large file attachments, mail that are missing headers or mail that do not conform to the mail RFC's can cause this

0x800CCC0B SERVER OR MAILDROP IS BUSY

1. Try to retrieve e-mail about once every 5 minutes. Alternatively, call your ISP help desk to make sure that the server hasn't crashed
2. You may be logged in on another machine. Close all connections on all machines, wait 20-30 minutes and then try again
3. Some mail servers will not recognise an improper disconnection. This will result in the account being 'Poplocked'. Either wait 20-30 minutes for it to time out or get somebody to shell into the mail server and stop the mail task that is running on the account. This can normally only be done with accounts that have UNIX shells
4. If you are not logged in on another machine or poplocked then someone may be using/downloading from your account or something is wrong with your account.

good luck!!
