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.

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?

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

Synchronize accounts produces loads of 0x800CCC0F errors.
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.
