Outlook Express and IMAP problems (0x800CCC0F)
 

Looking for some guidance. Or aspirin :-)

Situation: 10 mailboxes on a Courier IMAP server.
Multiple users on multiple locations, all sharing all mailboxes.

The aim is to use Outlook 2003.
Couldn't get that operational at all, so for the time being, we
settled for Outlook Express instead.

Synchronize accounts produces loads of 0x800CCC0F errors.
More specific: at quiet times, I am able to sync each mailbox
individually without any error.
Once I try to sync all accounts at once, loads of errors are
reported, on random mailboxes and even when I just finished an
individual sync.

I can access all mailboxes using Pegasus without any error.
(No, switching to Pegasus is not an option. Sorry!)
And no, even with Norton Internet Security switched off, the
problems persist :-)

Questions:
- Is this setup a very unusual one ?
- Is there someone out there, running a similar setup without
problems ?
- Any hints on the cause of these problems ?
Somehow all problems seem linked to Outlook / OE. But it is
rather unlikely that all users run exactly the same versions.

Thanks!

Often, the problem is caused by having an antivirus program settings to scan
incoming email. Disabling the option does not leave you unprotected and it
should be disabled. If that does not solve the problem then review the info
in this KB article for some other ideas:

By mailboxes I presume you are referring to IMAP folders. I doubt that you
are logging in to ten different IMAP accounts.

The default Courier-IMAP server configuration permits a maximum of five
simultaneous connections from the same IP address.

It appears that your mail client opens a separate connection for each IMAP
folder. The server refuses to accept any more connections, after the first
five, and then your mail client vomits all over itself.

Either increase the maximum number of allowed simultaneous connections, in
the server's configuration file, or switch to a different mail client that
implements IMAP properly.

Sam's reply was as follows (but since he used encryption w/o providing the
key, you may have missed it):

Well, good question. But I guess we are :-)
There are 10 different email addresses on the server, each with
it's own mailbox and set of log in codes (and it's own aliases).

The default Courier-IMAP server configuration permits a maximum of five
simultaneous connections from the same IP address.

Before we could get this schema going the server's administrator
had to adjust something from 5 upwards. Now it is set to 100
instead. (Due to NAT up to 3 different PCs could be calling the
server from the same IP, so that would make 30 connections.)

It appears that your mail client opens a separate connection for each IMAP
folder. The server refuses to accept any more connections, after the first
five, and then your mail client vomits all over itself.

There definately is going something wrong. Peeking at the
communications shows [TCP Window Full] [TCP Out-of-order]
messages. I never see an indication of a connection being denied
though.

Either increase the maximum number of allowed simultaneous connections, in
the server's configuration file, or switch to a different mail client that
implements IMAP properly.

The first has been done already, I think. And the second is, I am
afraid, not (yet) an option.
Thanks!

The problem only occurs with IMAP, not with POP3.
I would expect that to exclude any hardware or communications
related cause.

Further testing shows, that running at a quet time and without
any firewall at all (augh!) let the errors disappear. So I will
start fiddling with the time-out settings.

Thanks Jim. Et merci Jousset!

That's not the reason he might've "missed" it.

The only reason he might've missed it would be if he was using broken
Microsoft E-mail virus propagation ****ware, that fails to properly
implement a ten-year old standard for digital signatures.

Jim,

The others aren't using OE as their newsreaders
so there may not be a problem for them. ; )

A surprise for me is that both Google Groups and
the web interface seem to have no trouble with Sam's replies.
E.g. normally both refuse to show "attachments".

BTW how does WM do with this case? EG

Hi Sam:

Hope you feel better, now that you've vented about MS. Have a great day.

No idea, Robert, since I've had problems with newsgroup subs in Vista.
Hopefully, the next build will be better but who knows?
