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:

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!

Update: By no means cured :-)

Fiddling with the timeout settings as Q813514 suggests does not
help. (And that comes to no surprise at all: the default timeout
is already a full minute. While total sync requires less than a
minute, normally.)

Next thing I tried: on a PC with only SP2's firewall: create an
exception for port 143. That should solve firewall related
problems, I suppose. But it doesn't.
Yet, totally switching off the firewall on that same PC allows me
to sync without any errors :-)

Now, for testing purposes, running a PC without a personal
firewall is OK. But for an office PC, that wouldn't be a real
option, would it ?

On a hunch, that XP Home's 5 connection limit might be
responsible, I installed XP Prof, on the very same machine.
Oddly enough, things don't get better. Far from it!
Even without any firewall or virusscanner I cannot even
synchronize an individual account without frequent errors.
So, having more connections available definitely make things
worse. Does that make any sense ?

May I tap once more on your knowledgable opinions?

Yes.

Or, to be more precise: IMAP communicates on port 143.

(SMTP still uses port 25. But there is never any mail in the
outbox. So that cannot cause any of the errors.)

Depends how the PC is connected to the outside world, if it's by any
sort of half decent router then that should provide the firewall
anyway.

Is there by any chance a router involved in the total equation? Is it a
LinkSys router? Have you searched for any updated firmware for it from the
manufacturer?

It sounds like it could be a configuration problem in your OE accounts. Let
OE make a connection, then click Tools|Accounts|Mail. In the connection
column, they should all show "Any Available". If not, double-click that
account, click Connection, then remove the check mark for "Always connect
using...". Then do the same for any news accounts you might have. OE will
then pass all control for Internet connections to Internet Explorer, and so
will use whatever configuration you have under Control Panel| Internet
Options| Connection. See if that helps at all.

The router involved is a PC, running Smoothwall (with patches 1
to 8).

It sounds like it could be a configuration problem in your OE accounts.

Quite unlikely, as the problems occur at all locations.
Accounts are created on different PC's, different locations,
different ISP's , etc.
The only thing they have in common is the administrator.
(And he is beyond any suspicion. Anyone know the smiley for an
aureole ?)

column, they should all show "Any Available".

Check :-)

No! Sorry :-) But I am very grateful for all suggestions though.

Also very weird is the fact, that there is a link with the
server's load. But although I can set the timeout value at 3
minutes, the whole circus crashes in a session that lasts 20
seconds in total.

At 5 PM, I can hardly get any mail at all. At 8 PM I can.
Without firewall, all accounts at once. With the firewall
enabled, just one by one.
