E-mail, chat, & VoIP forum: Outlook error 0x800CCC0F

If not, there are simple emails that cause all current versions of Microsoft Outlook and Express to hang.

Sorry, but no fix is available. Just turn off preview in the Inbox and Deleted boxes.

Bob

All notes that come from "Unknown" get hung up and everything after that email stays on the server. I have to check Webmail several times a day. When you say "Preview" do you mean AutoPreview? Mine is already off.

Thanks,
Nancy

I just had the same issue with my pop server pop.1and1.com. I'm using OL2003.

I had to delete the junk mail through webmail and as soon as I deleted the offending email the rest poured into my Outlook.

I would like to know, if it is Outlook that is halting or is it the pop server?

I've seen it choke on malformed email. Well, that's not quite correct, is it? I'd rather not dive too deeply into this, but Microsoft is not known for handling errors.

Bob

Hi all,
Pls guide me how to fix this problem -> 0x800ccc0f.

You are noting another email client that hangs up.

My bet is that some SPYWARE is at play and your post didn't share what you do about it.

Bob

The usual Spybot, Adaware and others are notable but I want to share a growing problem with you.

BOGUS SPYWARE COMPANIES. Read http://netrn.net/spywareblog/archives/category/rogue-anti-spyware-software-and-sites/

They reveal the link to this list so you can avoid known bad companies. Its just sad so many are having this issue.

You may have spyware if Spybot fails. Here's why. Newer spyware and malware are specificly crafted to give spyware removal tools a hard time. If you can't run Adaware, Spybot and such, then run to the Virus and Security Forum and post about it since this is the topic every day.

Hope this helps,

Bob

If you think there is nothing wrong with your machine, go setup another POP3/SMTP account that is not on your ISP.

With the spam flood levels at all time highs, I'm beginning to think that some of these errors are simply email servers that at maxed out.

ISP's are sadly ill-equipped most of the time and can't help the millions they serve.

Bob

Bob, guess what, the crazy thing is working now. Maybe the server was just overloaded with requests. Anyway I am back up and running.

RK

The setup or exact steps are defined by what Email Client you are using plus you ISP or server's instructions. I can not know this.

Bob

If you are running Norton and this happened after December 6, 2004 it could be a Symantec bug. Go to

for a fix titled
Error: "Your email message to <email address of recipient> with the subject <email subject> was unable to be sent . . ." (1003,9) after running LiveUpdate.
It worked for me after I found it after spending 2 days doing various configuration settings and reinstalls.

Bob,

I woke up before the birds this morning and decided to try and solve this Outlook error 0x800CCC0F once and for all.

I am running my own mailserver. Unfortunately I have experienced this error for *years* now.

I have read most of the posts in this forum and numerous links in Google and so far I have not seen anything I have not already tried - but so far none of the solutions have worked for me or others using my mailserver.

KEY: The one solution (not really a solution) that ABSOLUTELY ALWAYS works is to continue clicking Send/Receive until Outlook makes the connection and sends and receives email. Be aware that I change absolutely nothing on mailserver or client but just continue clicking Send/Receive and eventually it works.

I have experienced the problem when the server is under load and I have experienced the problem on multiple machines when the server is under no load.

I have also seen Outlook work fine when the server is under load.

I have experienced the problem on inhouse client computers behind the firewall. Other users of my mailserver have experienced same error from outside the firewall - multiple people using different ISPs.

I have experienced the error on several machines including Win98SE, Windows NT, Windows 2000, Windows XP running various versions of Outlook including Outlook 97, Outlook 2000, Outlook 2003 and various versions of Outlook Express. I have experienced the problem on machines running various versions of Norton Anti-Virus, Norton Firewall, Norton Internet Security.

At this point in my mind, the problem is with Outlook/Outlook Express. The reason I think this is because I can be experiencing the problem on a machine running Outlook/Outlook Express - and at the same time check mail against the same server using Mozilla Thunderbird email client from another machine and it works fine. In fact while Outlook is trying and dying slowly as it checks 4 mailboxes, I can click Mozilla Thunderbird's Get Mail button as fast as I can and it will not fail or even hiccup. In fact it checks against the server so fast without failing that I can not even read the status messages coming from Thunderbird as it polls the mailbox.

I have been using Outlook/Outlook Express for years. I have only been running Mozilla Thunderbird for a couple of months but so far I have not seen Thunderbird cough up this error - not even once.

At this moment, the mailserver is under load (refusing requests to connect from known spam senders) and machine running XP Home SP2 and Outlook 2003 is failing and at the same time, from a different machine running XP Pro SP2, Thunderbird, I am clicking the Get Mail button in Thunderbird as fast as I can and it is not failing at all (one time it was a little slow in checking the mailbox but completed without an error).

Also all of the machines I have are fully patched and I am running Ad-aware SE on all of them. Ad-aware has never refused to run on any of them but it almost always finds spyware - even on a freshly formatted machine that has done nothing but have Windows loaded and get updates from Microsoft and then load Ad-aware and run it.

I simply must conclude the problem is Outlook/Outlook Express and this is distressing because the software is so ubiquitous and while it will be relatively easy for me to disable Outlook/Outlook Express and install Mozilla Thunderbird on my own machines, it will not be so easy to convince other people using my mailserver to do that.

To everyone reading this, I would try running Mozilla Thunderbird which is freely available at www.mozilla.org or try some other mail client such as Eudora to see if it solves your problem once and for all.

By the way, I do *not* work for Mozilla nor am I affiliated with them in any way other than using their software.

If you can't switch away from Outlook/Outlook Express, then try not changing anything on your computer and just keep on clicking Send/Receive and see if eventually (may take 20 times over 10 minutes) it will successfully send and receive mail.

I am very curious to know if my experience correlates with other's experience in this error/solution.

Hope this information helps everyone.

Rob

I have completely removed anti-virus software, and have installed a brand new modem. Everything is working well, except that I cannot send e-mails. I can receive e-mails, but cannot send them. I am running Windows ME and Outlook Express 6. Any help would be appreciated. Has anybody uninstalled Outlook Express and then reinstalled it? P.S. No matter how many times I hit send/receive button, I cannot get e-mail to send.

trouble shooting tips that I picked up from a Google search of 0x800ccc0f. Don't know but maybe something will be of help.

Something must have changed. Hope this helps!

I've got Symantec Antivirus Corporate Ed 9.0.1 installed on a server that updates virus defs for 7 client PC's in my home. I've got the Alert Management server set to send an email to myself if a virus is detected on any of the machines. I use Comcast as my ISP and have tried using the same reply to address as the send to address, a fake reply to, and a reply to of another valid account. All with the same results. I can send email, but when it tries to receive, I get the same error everyone else in this thread complains about. If I got to my Web Email, I can see the message, and I must delete it out of the inbox and out of deleted items before I can receive email from Outlook again. This only happens with messages from my AV server, never get them from anywhere else. This was working fine up until about the end of 2004 (Oct-Nov?)Funny that it will pull into my webmail fine, but not Outlook. I'm using Outlook 2003 with XPpro, all updates and patches. Probably some "patch or fix" that was applied that caused it, but I'll be damned if I can find any cause for it.
