Outlook Error 0x800ccc0d is simply a failure to connect - that's in the error message. How to fix Outlook Error 0x800ccc0d involves a little investigation.

I am unable to get my e-mail from outlook express - I keep getting this error: 0x800ccc0d. What does it mean, and what do I do about it?

Outlook and Outlook Express both report that error number when they can't find or connect to your mail server.

Understanding what's happening is fairly easy. Fixing requires some additional information.

I'll focus here on Outlook Express, but similar steps are appropriate for Outlook as well.

Typically you'll see an error message much like this:

Outlook Express error 0x800ccc0d box

Unfortunately, many people seem to fixate on the error number at the end - 0x800ccc0d. While that can be useful, and it's easy to search on, they're missing all the additional information that Outlook is providing in the error. Specifically, this:

The host '' could not be found.

That's a big clue as to what's going on. Your email account is configured to retrieve email from the server '' (a fictitious server I made up for this example), and Outlook Express cannot connect to that mail server.

Step one? Make sure you can connect to anything else on the internet - any web page will do. Error 0x800ccc0d can occur because you're not connected to the internet at all, and visiting any random web page simply verifies that your internet connection is working.

If your internet connection is not working, that has nothing to do with Outlook, Outlook Express or error 0x800ccc0d. Your mail failure is just one symptom of not being connected to the internet.

If you are connected, step 2 is to validate your Outlook Express account configuration. Specifically, if you click on the Tools menu in Outlook Express, then click on the Accounts menu item, and then in the resulting dialog box click on the Mail tab, you should see something like this:

Outlook Express Accounts Dialog

"If the Incoming Mail (POP3): setting is wrong, then error 0x800ccc0d can result."

If you have more than one account, you may see multiple items in the list. Click on the one with which you are having trouble and click on Properties. In the resulting dialog box, click on the Servers tab and you should see something like this:

Outlook Express Account Properties Dialog

Note the arrows pointing at the two instances of the mail servers you would be using: one for POP3 (incoming email) and one for SMTP (outgoing email).

If the Incoming Mail (POP3): setting is wrong, then error 0x800ccc0d can result. In fact, the error message you got originally, "The host '' could not be found." is telling you that the mail server specified here could not be contacted.

So, what do you do?

I can't tell you what this setting should be, because it varies from ISP to ISP. What I use is different from what you use. So, you'll need to double check the information you were given from your ISP to see what they said your mail server name should be. Make sure you've entered that exactly. In fact, it probably makes sense to double check your entire configuration while you're here.

It's also possible that your mail server may simply be down - the ISP could be having trouble, for example, or the ISP could have changed mail servers. You'll need to contact your ISP to determine if this is the case, and whether or not they have an alternative mail server you can use, or how long you might need to wait for things to be fixed.

I see the same error message about once a month.My POP servers are correct and I just reboot to fix this problem. I've always wondered why I have to resort to this procedure but it works.

October 1, 2006 4:54 AM

I was getting this error almost daily and tech after tech at my ISP couldn't figure out why. A few of their suggestions would have been hilarious if I wasn't paying for a supposedly good service. Eventually, a supervisor figured out that as an anti-spammer measure, they count total numbers of recipients for the e-mails I send per day. Because I am in a private e-mail discussion group of 17 people and some days we post a lot back and forth, I was exceeding the limit and they were automatically suspending my sending of e-mails for a while. They agreed I'm not a spammer and raised my limit and the problem hasn't happened since. Their default limit was 250 recipients per day, but now I'm allowed 5000, which I'll never come close to. ZoneAlarm makes sure my system won't send messages to more than 30 people at a time, so even if my computer were infected (despite my firewall, AV programme, etc), the new limit won't be taken advantage of for spam. I don't know how many ISPs have that kind of daily limit, but no doubt some do. If others keep getting that error, it's something to ask tech support about, although if they're like my ISP, you may need to deal with a higher level tech or supervisor.

i have encountered this error and ihave done all troubleshooting regarding server settings and account infor mation but still i have the same error. then i have experimentally turn off the antivirus and my outlook express works.

Ivor Duarte
May 29, 2007 2:52 AM

This error can arise because the automatic updating system of your antivirus has reallocated port 110 &/or port 25 to its own server. In this case you will get an error message mentioning the antivirus maker's server. Solution in this case may be to uninstall the antivirus and try a different one. I had this problem with AVG Professional, unfortunately after I uninstalled it the 110 error problem was still there because the registry settings had been changed by the antivirus programme. However my email did still work even though I had the error code 2/3 times a day. It is possible that your antivirus supplier could help you if they are prepared to admit there is a problem. Otherwise uninstall Outlook Express and reinstall it.

I installed Outlook Express 2000 on Windows Vista. Unfortunately, I typed the wrong name under the outgoing server (extra character). I went to properties for that account, changed it, but when I hit send receive, it is still looking for the first, erroneous name. I then removed the account completely, got out of Outlook, re-opened, recreated the account from scrath, but I hit send and there it goes giving me the 0x800ccc0d error because it still "remembers" the wrong name I entered originally, even though the account was deleted. Thanks for your help.

Thank you, Thank you. I was just about to reinstall Windows. I could not retrieve my MSN email. If anybody is having trouble the new servers are POP3.LIVE.COM & SMTP.LIVE.COM
These servers replace the old
I'm glad I've found Leo... thanx again

Great comment!
Would you agree then, that if this error occurred in my computer after the ISP Server has changed its settings, their settings might be just not right? Our network recently changed to having proxy-settings and automatic IP-Addresses and using a server machine. Would you be able to tell those nosebears how to configure port liberation in a way that allows me to use it? They say they liberated ports 110 (Pop) and 25 (SMTP), however, it does not help. 11004 continues. By the way, spybot also cannot download updates anymore, naming 11004 too.

November 8, 2007 1:49 AM

I have this error because I entered the pop details incorrectly. Every time I try to open Outlook express I get this message and then outlook freezes so I am not able to correct my error. Is there any way to alter the pop information I have entered without opening outlook express?

November 17, 2007 2:56 AM

See my commet above. Yes, it was the ISP server, they had not correctly configured access (gatway!) by DHCP. Your comment "simply a failure to connect" helped a whole lot, because it made me go on and on with the server people, and after three weeks they finally reconfigured, and now it is fine. Thank you!

I have worked with Outlook Express alot, and also with the newer version called windows mail on the Vista Operation system. I have found that when you use certain kinds of virus scan programs such as (Norton) that the program likes to change settings for you wether you want it to or not. When this happens, disable the program and if that fixes it, then you have found the problem. Now you might want to disable the spam filter or other part of that program that is the problem. In my experience with it, usually if I have the virus scan set up to ONLY scan for virus's, then it will be ok.

I have spent at least three hours with Comcast tech people. I no longer can get Comcast to connect with my Outlook Express 6. My problem is with my wifes computer which is Intel (R) Pentium (R) 4 CPU 2.66 GHZ, process ore speed 2.60 Ghz, Ram 512 MB, Windows XP Home, opeerating system version5.1.2600 which is automatical set to download Microsoft info. HOWEVER - this computer has been used in a little bit different ways as far as Outlook Express. At one time it contain over 3000 emails in the inbound box and pbly should not even worked. All of a sudden it quit connecting. Comcast suggest I take a portion of the 3000 emails and put them in a new file, I did. Shortly after that the 1700 emails in the in box completely disappeared. Now there should be no reason that it should not connect with Comcast. Instead all the emails seem to be going into the Comcast Web mail. This email is very confusing and difficult for my wife to operate and wants to get Outlook Express going again. I have looked at a bunch of cure-all programs and they seem to confuse me more. Is there another email program much like OE that you would suggest converting to. You have helped me before and I do keep fwdg you new letter of many of my email friends. Hope they get started with you. Thanks again. Bud M

Most of the problems in outlook and outlook express are resolved by merely restarting the computer.

I also was getting Outlook Express error 0x800ccc0d which basically was telling me I had no internet connection. If I tried to use Internet Explorer I would get 'Page not Found' and if I clicked on the 'run diagnostics' option under 'Page not Found' I would get Error 12007. I could get rid of this conditon by resetting the computer, or by turning it off and then back on again. It would work for about 10 minutes, and then, the same problem would occur. The resolution was to run a 'Registry repair/Cure' program that I downloaded for agbout $12.00. This program found registry problems and was able to fix them. After that, my computer worked fine. I would say that 'Reg Cure' fixed my problem.

I can't receive email. I keep getting a similiar message to the one above except it's:

The host '' could not be found. Please verify that you have entered the server name correctly. Account: '', Server: '', Protocol: POP3, Port: 110, Secure(SSL): Yes, Socket Error: 11004, Error Number: 0x800CCC0D

It started after I switched over to Verizon for my internet. It happened on my Grandmother's computer and she had to use Verizon webmail for a while until it was resolved.
Thanks for your response,

This error message means that Outlook Express can not find host/can not locate server.
a. Go to Tools--Options--General Tab and untick this option.
b. Check your SMTP settings is correct or not.
c. Make sure your network does work properly. Check DNS numbers, remove and then reinstall TCP/IP in Control Panel-Network.

May 26, 2010 9:32 AM

Hi There
I have three email accounts in Outlook Express.

All three from different ISP's

Two work perfectly fine, this post is reference the non-working one.

The email address ****

For some unknown reason the pop3. and the smtp setting do not now work hence the error code:-

The host '' could not be found. Please verify that you have entered the server name correctly. Account: '', Server: '', Protocol: POP3, Port: 995, Secure(SSL): Yes, Socket Error: 11004, Error Number: 0x800CCC0D

I have tried all sorts of variables.

I can actually access my email from their ISP but this is where I come unstuck all the time there is no "contact us" facility, just enter "email address" and "password"

So I am going round and round in circles.

Any help would be much appreciated


August 31, 2010 12:09 AM

POP3 setting is right though same message arise. please guide me for the same.

I have been 3 weeks and tried everything, including an hour on the phone to sky. help before I go mad......All my settings are correct pop 3 is set to 995 etc and checked, checked and double checked. I can only get my emails from the sjy website. It has worked fine for over two years. I ge this message.

The host '' could not be found. Please verify that you have entered the server name correctly. Account: '', Server: '', Protocol: POP3, Port: 995, Secure(SSL): No, Socket Error: 11004, Error Number: 0x800CCC0D

"" doesn't sound like a common server name. Triple check that is all I can offer.

August 26, 2011 9:25 PM

i am having problems with my outlook express email the same 0x800ccc0d comes up. do i put at the or just example. i cant even get the webmail to work now.

I have to see the entire message to know exactly what is been misconfigured. Check the instructions you received from your ISP for the proper settings.

Unless he is using the paid version of Yahoo Mail, it is not possible to access mail using an email program such as Outlook Express. If he is using a paid version, it would be necessary to get the correct settings from the Yahoo website.

Concerning Outlook Express in general, it is known to have many problems that will not be resolved because Microsoft has
discontinued all support for it. We now recommend that you
move to a different email program.

I'd strongly suggest you read this article for more

More than likely you need to adjust your SMTP settings, which are the settings that send email. You can get the proper settings from your Internet provider. More in this article:

Hi Leo...0x800CCC08 - can't find host. I ping'd the mail server and it is unable to find it aswell. We can access the internet, but no email capabilities.
ISP provider checked the DNS - everything is pointing correclty.
We have an internal firewall to our email (port is 25, incoming 110) We can't get anything out or in?

dears sir. maybe it has been a long time since i went to school, however when i went to school i was told that in a presentation you always explain what abreviations are first before yo use them. people new to computer land ( and there are billions of them that do not own or have acsess to them) may not understand what the abbreviations you so eagerly throw about mean.
so decoding your abreviations for some people will not be fun. please in the future have the courtacy to explain that ISP might mean internet servous provider. or maybe explain what pop3 means. this language you use might be common or easily understood to you, however it might as well be sand script for some people.
it is also helpful to explain what the computer is trying to do and what is not happenning so a person can understand the problem.
to a car mechanic trying to help a person who's car is not starting may ask for a sound it was or is making, or do ther things to narrow the problem and explain what each step is for and why. sure the problem may not be fixxable over the phone but a person may find out it is a loose battery cable or a fuse or the problem is deeper such as a burnt out starter.
your explaination for "wrong mail sever" is about as helpful as asking a person with a car problem ,what color there car is.
that is of course if you understood wctci means what color there car is.

July 30, 2012 12:25 PM

I think I have tried everything and still get the error and also this one 0x80070002. Can you help? I understand the ISP etc.

January 13, 2013 4:54 AM

I had the problem.
I use Outlook 2007, and solved it by not defining a mail account of type Exchange/POP3/HTTP, but of type Other. Then I had the opportunity to select Microsoft Outlook Hotmail Connector.

After this, everything worked fine for me.

I used Outlook Express since 2002 on my Bellsouth, then ATT ISP. I had been using Dell with XP sp3 and a also later new little Asus with XP and office. Then when ATT attached to Yahoo all began to screw up. I know MS and ATT and Yahoo want me to get the most recent upgrades so they won't have to support earlier versions. ATT did so far as to say that if I had a certain account before a certain date I could continue to use Outlook Express. But if after that, could not. (probably associated with att web mail, yahoo driven. How would I determine if i actually had the referenced account by such date? I simply want to be able to access my email by both webmail and OE. Eventually I might go to Gmail or other and also want to access thru OE. At best, I get good preceding steps (going by ATT email support page printed as of 12/20/2012) but error message Cannot Log onto incoming mail Server, crops up. Also several times MSOE Cannot Initialize may show up in subsequent step. Am so teed off at ATT may just change to Charter. I do not want to have to dive into Registry, Any help greatly appreciated.
