0x800CCC00 - Authentication did not load
1. Reboot your computer and try again
2. Check Service Status for mail problems
3. Setup a new account in Outlook Express, re-entering your mail connection details. It is possible that your account has become corrupt
0x800CCC01 - Invalid certificate content. / 0x800CCC02 - Invalid certificate date
The digitally signed email cannot be verified using the available digital certificate. Either the digital certificate is out-of-date or has been cancelled. Get your certificate re-issued by your certificate authority or try recreating your mail profile.
0x800CCC03 - User already connected
The mailserver believes that you are already logged into your mailbox:
1. Close all connections on any machines that you connect to your email with and wait 20 minutes to check again
2. If you are not logged in on another computer then someone may be using/downloading from your account, or something is wrong with your account
3. If the problem continues, recreate your mail profile
0x800CCC05 - Not connected to server
Outlook Express can't talk to the mailserver.
1. Check you are connected to the internet (view a webpage). If you are connected, double-check your mailserver address
2. If you can't view webpages, re-connect and try again
0x800CCC0A - Incomplete
1. This is a possible corruption of the file that records which emails you have downloaded. Close your internet connection and all programs. Search for the file 'pop3uid.dbx' and rename it to 'pop3uid.xxx'. Reconnect and try again
2. If this doesn't work, reboot and try again
3. It's possible that the error is being caused by an email waiting to be downloaded from the mail server. For POP3 mail try using webmail to view the contents of your mailbox. This may help identify the problem - if you see emails that you have already downloaded, try deleting them and the next in the list and try downloading using Outlook Express again. Your mail should then function properly
0x800CCC0B - Server busy or incorrect domain on sender's email address
1. The mailserver may be slowing down because of heavy email traffic. Wait 5 minutes and try again
2. If the problem continues check the service status page to see if there is a known problem with email service
3. Check your email settings and make sure you are using the correct format for your email address
0x800CCC0D - Cannot locate server
Outlook Express can't see the mailserver.
1. Check you are connected to the internet (by viewing a website with your web browser). If you are connected, double-check your mailserver address
2. If you can't view webpages, re-connect and try again
0x800CCC0E - Cannot connect to server
Outlook Express can't talk to the mailserver.
1. Check you are connected to the internet (by viewing a website with your web browser). If you are connected, double-check your mailserver address.
2. If you can't view webpages, re-connect and try again
0x800CCC0F - Connection closed
Your modem/network was disconnected. If this happens often with dial-up there may be noise on your phone line or you may need updated modem drivers. With a network (broadband etc) the problem may be with your network hardware or drivers. Also check that any antivirus software you have installed is working correctly.
0x800CCC10 - Address not known on server
Outlook Express can't deliver an email because the address appears invalid. Check your spelling of the address (a common error is using a comma instead of a full stop in domain names) and try again. If there is one particular message causing a problem, delete it from your Outbox (or move it to your Drafts folder) and try again to verify this is the case.
0x800CCC11 - Mailing list not known on server
Outlook Express can't deliver to a mailing list, possibly because one of the email addresses isn't valid (check the spelling). Lots of mailing lists have restricted access, make sure that you are properly subscribed to the list.
0x800CCC12 / 0x800CCC13 / 0x800CCC14 / 0x800CCC15 - Winsock problems
This error usually means that a problem has occurred in your network protocols which is making it impossible for Outlook Express to transmit data over the network. A common fix is to re-install TCP/IP. First try rebooting your PC as this will often fix the problem.
0x800CCC16 - User account not recognized
1. The most common cause for this is incorrect username and password details
2. If they are not wrong, try setting up another identity with the same details. Sometimes accounts become corrupted. Creating a new copy of your email account can fix the problem
0x800CCC17 - User cancelled operation
This can occur if you cancel the sending and receiving of emails. Try rebooting your computer.
If this problem continues, the file 'pop3uidl.dbx' that logs which emails have been received may have become corrupt. You can do a search for the file and rename it 'pop3uidl.xxx' then restart your computer.
[Top]
0x800CCC18 - Logon attempt failed.
This simply means that Outlook Express was unable to log into your mail account.
1. Check your account information (username, password and mailserver addresses)
2. Make sure your account is still active (try and login to the portal and check your mail using the Webmail tool)
0x800CCC19 - Timeout
This error may be the result of a temporary glitch. Try rebooting your system and trying again. If this problem continues, the file' pop3uidl.dbx' that logs which emails have been received may have become corrupt. You can do a search for the file and rename it 'pop3uidl.xxx'. Then reboot your system and try again
0x800CCC1A - Unable to connect using SSL
This error indicates a problem connecting using the Secure Socket Layer. Remove this setting by editing your account settings and looking in the advanced tab.
General Errors- Applies to many of the errors on the above lists
Many errors can be fixed by rebooting your computer. Many problems are also caused by antivirus software not updating correctly.. We recommend that you take a look at Microsoft's Knowledge Base regarding Outlook Express problems if your problems persist.
POP3 (Post Office Protocol 3) Errors
Problems that occur with POP3 affect the download of your emails. These problems occur, either because of a temporary glitch, file corruption, or because your account details are incorrect.
Checking your connection details are correct
Have you changed your account details recently? Make sure that you are not using CAPS LOCK while entering a case sensitive password. There is a quick way to check that you are using the right password and username, by connecting to the internet and using a program called a telnet client.
Telnet is program that allows you to access and talk to other computers, in this case you can pretend to be Outlook Express and talk directly to the mailserver. This will allow you to see if it's your email account or Outlook Express that is at fault. This should work with most versions of windows, although in Windows Vista you will need to add Telnet manually or download a different telnet program, such as Putty.
1. Click the Start button, then RUN
2. In the RUN prompt, type 'cmd' (on Windows NT/2000/XP) or 'Command' on Windows 95/98/ME
3. In the new window, type 'telnet mail.plus.net 110' then press enter. Take care in your typing as you may not see what you type so its easy to make a mistake. If you do, it's best to start again
4. You should be connected to the mailserver - you should see the response +OK Hello there which confirms the mailserver is OK
5. Type in 'user your username' and hit the enter key (if your username was jsmith you would type 'user jsmith' )
6. You will then get a message +OK Password required - type in 'pass your password' and press enter (If your password was opensesame you would type 'pass opensesame')
If it is correct, you will get an '+OK Well done' message. You are now in your mailbox and can be sure that your email account details are correct.
SMTP (Simple Mail Transfer Protocol) Errors
Problems that occur with SMTP affect your sending of emails. These problems can occur because of a temporary glitch (such as another program blocking port 25 which is used by Outlook express to send emails). It is possible that the outgoing mailserver address is wrong. This should be relay.plus.net. This is the first thing you should check.
Testing your access to port 25
You can check to see if your email is being blocked by using a telnet client. If you can connect to the outgoing mailserver on port 25, this will confirm that your problem mostly likely lies with the Outlook Express application, or your settings. To do the test:
1. Click the Start button, then RUN
2. In the RUN prompt, type 'cmd' (on Windows NT/2000/XP) or 'Command' on Windows 95/98/ME
3. In the new window, type 'telnet relay.plus.net 25' then press enter. Take care in your typing as you may not see what you type so its easy to make a mistake. If you do, its best to start again
4. You should be connected to the mailserver - you should see a response that begins with "220." which confirms the port 25 is open. If you don't get the "220" response, either the mailserver is not operating properly (check service status), you're not connected to the internet or something on your system may be blocking port 25
If you run your own mailserver and don't limit access to it, our network engineers may have blocked your access to port 25. You will be contacted by support if this happens.
NNTP (Network News Transfer Protocol) Errors
NNTP allows Outlook Express to function as a USENET (newsgroup) client. Problems with NNTP will mean that you either cannot post to newsgroups or are unable to download the latest posts. In most cases problems will be as a result of incorrect settings or a corrupt news posting. You can check your settings by reading the guide to setting up Outlook Express for newsgroups. If there is a problem with USENET service, it will be indicated on the Service Status page.
IMAP (Internet Message Access Protocol) Errors
IMAP allows Outlook Express to store emails on the mailserver, allowing access to all your email, old and new from anywhere you can access email. Problems that occur with IMAP are mostly the same types of problems that occur with the more common POP3 mail system. If you were intentionally using the IMAP service, make sure that your settings are correct.
Because IMAP stores all your emails on the mailserver it is possible that a corrupt email (often with large attachments etc) may be the cause of problems. If you think this has occurred, raise a Question to our Support Team using the Help Assistant. Our network engineers will then investigate further.
RAS/DUN (Remote Access Server/ Dial-up Network) Errors
RAS/DUN errors indicate problems with your dial-up or network system. Outlook Express is tied to your dial-up settings, so if you open it, while not online, it can either automatically connect, or give you the option to connect. You should check your connection settings within Outlook Express
(Click Tools, Options, Connections, Change - to see your settings).
Winsock (Windows Socket/ Socket2) Errors
Winsock is the windows component that Outlook Express uses for all its TCP/IP (internet) communication. Winsock errors are usually caused by problems within the application/ operating system, sometimes as a result of bad configuration. They may be temporary in nature, vanishing on a reboot. They may be the result of a corruption within either Outlook Express or Windows.

WINSOCK_WSAEINPROGRESS Operation now in progress.
0x800CCC00 - Authentication did not load
1. Reboot your computer and try again
2. Check Service Status for mail problems
3. Setup a new account in Outlook Express, re-entering your mail connection details. It is possible that your account has become corrupt
0x800CCC01 - Invalid certificate content. / 0x800CCC02 - Invalid certificate date
The digitally signed email cannot be verified using the available digital certificate. Either the digital certificate is out-of-date or has been cancelled. Get your certificate re-issued by your certificate authority or try recreating your mail profile.
0x800CCC03 - User already connected
The mailserver believes that you are already logged into your mailbox:
1. Close all connections on any machines that you connect to your email with and wait 20 minutes to check again
2. If you are not logged in on another computer then someone may be using/downloading from your account, or something is wrong with your account
3. If the problem continues, recreate your mail profile
0x800CCC05 - Not connected to server
Outlook Express can't talk to the mailserver.
1. Check you are connected to the internet (view a webpage). If you are connected, double-check your mailserver address
2. If you can't view webpages, re-connect and try again
0x800CCC0A - Incomplete
1. This is a possible corruption of the file that records which emails you have downloaded. Close your internet connection and all programs. Search for the file 'pop3uid.dbx' and rename it to 'pop3uid.xxx'. Reconnect and try again
2. If this doesn't work, reboot and try again
3. It's possible that the error is being caused by an email waiting to be downloaded from the mail server. For POP3 mail try using webmail to view the contents of your mailbox. This may help identify the problem - if you see emails that you have already downloaded, try deleting them and the next in the list and try downloading using Outlook Express again. Your mail should then function properly
0x800CCC0B - Server busy or incorrect domain on sender's email address
1. The mailserver may be slowing down because of heavy email traffic. Wait 5 minutes and try again
2. If the problem continues check the service status page to see if there is a known problem with email service
3. Check your email settings and make sure you are using the correct format for your email address
0x800CCC0D - Cannot locate server
Outlook Express can't see the mailserver.
1. Check you are connected to the internet (by viewing a website with your web browser). If you are connected, double-check your mailserver address
2. If you can't view webpages, re-connect and try again
0x800CCC0E - Cannot connect to server
Outlook Express can't talk to the mailserver.
1. Check you are connected to the internet (by viewing a website with your web browser). If you are connected, double-check your mailserver address.
2. If you can't view webpages, re-connect and try again
0x800CCC0F - Connection closed
Your modem/network was disconnected. If this happens often with dial-up there may be noise on your phone line or you may need updated modem drivers. With a network (broadband etc) the problem may be with your network hardware or drivers. Also check that any antivirus software you have installed is working correctly.
0x800CCC10 - Address not known on server
Outlook Express can't deliver an email because the address appears invalid. Check your spelling of the address (a common error is using a comma instead of a full stop in domain names) and try again. If there is one particular message causing a problem, delete it from your Outbox (or move it to your Drafts folder) and try again to verify this is the case.
0x800CCC11 - Mailing list not known on server
Outlook Express can't deliver to a mailing list, possibly because one of the email addresses isn't valid (check the spelling). Lots of mailing lists have restricted access, make sure that you are properly subscribed to the list.
0x800CCC12 / 0x800CCC13 / 0x800CCC14 / 0x800CCC15 - Winsock problems
This error usually means that a problem has occurred in your network protocols which is making it impossible for Outlook Express to transmit data over the network. A common fix is to re-install TCP/IP. First try rebooting your PC as this will often fix the problem.
0x800CCC16 - User account not recognized
1. The most common cause for this is incorrect username and password details
2. If they are not wrong, try setting up another identity with the same details. Sometimes accounts become corrupted. Creating a new copy of your email account can fix the problem
0x800CCC17 - User cancelled operation
This can occur if you cancel the sending and receiving of emails. Try rebooting your computer.
If this problem continues, the file 'pop3uidl.dbx' that logs which emails have been received may have become corrupt. You can do a search for the file and rename it 'pop3uidl.xxx' then restart your computer.
[Top]
0x800CCC18 - Logon attempt failed.
This simply means that Outlook Express was unable to log into your mail account.
1. Check your account information (username, password and mailserver addresses)
2. Make sure your account is still active (try and login to the portal and check your mail using the Webmail tool)
0x800CCC19 - Timeout
This error may be the result of a temporary glitch. Try rebooting your system and trying again. If this problem continues, the file' pop3uidl.dbx' that logs which emails have been received may have become corrupt. You can do a search for the file and rename it 'pop3uidl.xxx'. Then reboot your system and try again
0x800CCC1A - Unable to connect using SSL
This error indicates a problem connecting using the Secure Socket Layer. Remove this setting by editing your account settings and looking in the advanced tab.
General Errors- Applies to many of the errors on the above lists
Many errors can be fixed by rebooting your computer. Many problems are also caused by antivirus software not updating correctly.. We recommend that you take a look at Microsoft's Knowledge Base regarding Outlook Express problems if your problems persist.
POP3 (Post Office Protocol 3) Errors
Problems that occur with POP3 affect the download of your emails. These problems occur, either because of a temporary glitch, file corruption, or because your account details are incorrect.
Checking your connection details are correct
Have you changed your account details recently? Make sure that you are not using CAPS LOCK while entering a case sensitive password. There is a quick way to check that you are using the right password and username, by connecting to the internet and using a program called a telnet client.
Telnet is program that allows you to access and talk to other computers, in this case you can pretend to be Outlook Express and talk directly to the mailserver. This will allow you to see if it's your email account or Outlook Express that is at fault. This should work with most versions of windows, although in Windows Vista you will need to add Telnet manually or download a different telnet program, such as Putty.
1. Click the Start button, then RUN
2. In the RUN prompt, type 'cmd' (on Windows NT/2000/XP) or 'Command' on Windows 95/98/ME
3. In the new window, type 'telnet mail.plus.net 110' then press enter. Take care in your typing as you may not see what you type so its easy to make a mistake. If you do, it's best to start again
4. You should be connected to the mailserver - you should see the response +OK Hello there which confirms the mailserver is OK
5. Type in 'user your username' and hit the enter key (if your username was jsmith you would type 'user jsmith' )
6. You will then get a message +OK Password required - type in 'pass your password' and press enter (If your password was opensesame you would type 'pass opensesame')
If it is correct, you will get an '+OK Well done' message. You are now in your mailbox and can be sure that your email account details are correct.
SMTP (Simple Mail Transfer Protocol) Errors
Problems that occur with SMTP affect your sending of emails. These problems can occur because of a temporary glitch (such as another program blocking port 25 which is used by Outlook express to send emails). It is possible that the outgoing mailserver address is wrong. This should be relay.plus.net. This is the first thing you should check.
Testing your access to port 25
You can check to see if your email is being blocked by using a telnet client. If you can connect to the outgoing mailserver on port 25, this will confirm that your problem mostly likely lies with the Outlook Express application, or your settings. To do the test:
1. Click the Start button, then RUN
2. In the RUN prompt, type 'cmd' (on Windows NT/2000/XP) or 'Command' on Windows 95/98/ME
3. In the new window, type 'telnet relay.plus.net 25' then press enter. Take care in your typing as you may not see what you type so its easy to make a mistake. If you do, its best to start again
4. You should be connected to the mailserver - you should see a response that begins with "220." which confirms the port 25 is open. If you don't get the "220" response, either the mailserver is not operating properly (check service status), you're not connected to the internet or something on your system may be blocking port 25
If you run your own mailserver and don't limit access to it, our network engineers may have blocked your access to port 25. You will be contacted by support if this happens.
NNTP (Network News Transfer Protocol) Errors
NNTP allows Outlook Express to function as a USENET (newsgroup) client. Problems with NNTP will mean that you either cannot post to newsgroups or are unable to download the latest posts. In most cases problems will be as a result of incorrect settings or a corrupt news posting. You can check your settings by reading the guide to setting up Outlook Express for newsgroups. If there is a problem with USENET service, it will be indicated on the Service Status page.
IMAP (Internet Message Access Protocol) Errors
IMAP allows Outlook Express to store emails on the mailserver, allowing access to all your email, old and new from anywhere you can access email. Problems that occur with IMAP are mostly the same types of problems that occur with the more common POP3 mail system. If you were intentionally using the IMAP service, make sure that your settings are correct.
Because IMAP stores all your emails on the mailserver it is possible that a corrupt email (often with large attachments etc) may be the cause of problems. If you think this has occurred, raise a Question to our Support Team using the Help Assistant. Our network engineers will then investigate further.
RAS/DUN (Remote Access Server/ Dial-up Network) Errors
RAS/DUN errors indicate problems with your dial-up or network system. Outlook Express is tied to your dial-up settings, so if you open it, while not online, it can either automatically connect, or give you the option to connect. You should check your connection settings within Outlook Express
(Click Tools, Options, Connections, Change - to see your settings).
Winsock (Windows Socket/ Socket2) Errors
Winsock is the windows component that Outlook Express uses for all its TCP/IP (internet) communication. Winsock errors are usually caused by problems within the application/ operating system, sometimes as a result of bad configuration. They may be temporary in nature, vanishing on a reboot. They may be the result of a corruption within either Outlook Express or Windows.
