Ever seen the cryptic "0x800ccc0f" error when trying to synchronize your IMAP folders in Outlook? The rather cryptic Microsoft errors are useless. There are literally hundreds of websites that discuss this issue and damn near everyone of them is also useless. This one is not.
If you've googled the error before, you're familiar with the most common suggestions - disabling your firewall and antivirus, make sure your computer is connected to the internet, make sure your computer is plugged in, make sure you're running Outlook...etc, etc, ad nauseum.
This problem had been plaguing a client of mine for months. Being well experienced IT people, my coworkers and I tried all the standard stuff. We couldn't replicate the problem on our home machines. We couldn't replicate it at our "real" jobs. We tried Outlook Express and varying versions of Microsoft Outlook (2000, 2003, 2007...) without any success at the client's location.
Our client has perhaps 20 workstations all sharing a fractional (half) T1 and all of which use off-site IMAP accounts. Our initial suspicion was that the fractional T1 was the problem, causing timeouts and what not, as their network experienced significant (>20%) packet loss during peak business hours. We tried the commonly suggested steps of increasing connection timeout inside of Outlook without any success. After convincing them to upgrade to a faster connection (a full T1) and arguing with the ISP (I don't care if it's full duplex, a T1 is damn slow) about connection speeds and quality, the problem persisted.
The email server they use wasn't under any particular strain, with low (<0.20) load averages and only minor bandwidth use. It runs Gentoo, so it was more or less hand configured, and nothing in the (rather verbose and quite large) /var/log/mail/info.log file hinted at what the problem could be. Even after flushing the firewall, the problem remained.
We use postfix, courier-imap, dspam, and clamav to provide their email services. All of these have worked quite well, with the exception of this particular problem. After tearing my hair out one night while revisiting our mail server configuration and this problem, it occurred to me that I hadn't ever looked at the actual IMAP configuration settings (in my defense the mail system was configured by a colleague.)
I pulled open the /etc/courier-imap/imapd file and started poking around. Indeed, the culprit was quite obvious:
My god, it defaulted to 4?! FOUR?! The 20 client computers (running Outlook and Outlook express, no less) sharing one fractional T1 line are going to use a hell of a lot more than 4 connections and probably more than 10 daemons. These defaults might be suitable for 1997 or for a small home personal network, but certainly not for a small corporation in 2007.
After increasing this and restarting the courier-imapd process, we haven't heard of a single case of Outlook and the infamous "0x800ccc0f" error code. So if you know anyone who's seeing this error, especially if they're behind a NAT shared with their coworkers (who also have the problem)...be sure to increase the connection limit!

Over the following months, Ner'zhul continued to experiment with his plague of undeath by subjugating every human inhabitant of Northrend. With his army of undead growing daily, he knew that the time for his true test was nearing.

Your IMAP server has closed the connection
We have the same problem on all of our company computers that run GMAIL/Outlook/IMAP. Google sent us a document that said that the Time to Live (whatever that is) for Google DNS is only 10 minutes. After that the DNS can change and windows will follow but Outlook will not. The solution they recommend is to restart Outlook. The issue on our computers sometimes occurs several times per day and sometimes not at all. I would love to hear of a workaround.
I am facing similar problem with my gmail IMAP account
When I am connecting my gmail IMAP account in Outlook 2007, I am facing the similar kind of problem but with different error code
"Your IMAP server has closed the connection. This may occur if you have left the connection for too long" after configuring an IMAP account.
Temporary System Error
Protocol: IMAP
Server: imap.gmail.com
Port: 993
Error Code: 0x800CCCDD
Same issue here with Outlook
Same issue here with Outlook 2003 sp3 and Gmail.
Please God someone find a workaround or at least an explanation!
One clue... someone suggested switching to thunderbird. I tried it. It seemed fine for a couple days, then IT started popping up very similar messages. can't remember exact wording there, but didnt love thunderbird enough to play with it much longer anyway.
Another hint. I also have my Windows Mobile phone syncing with my Gmail IMAP account. It occassionally has problems logging in too, but not as often or as clubsily as Outlook on the laptop (but could it be the multiple access IP's that Gmail is barfing at? they won't admit it nor do they seem to care, they just tell you to make sure you spell your password correctly and retarded stuff like that).
Anyone?
