Hi there, I would like to know if somebody were able to solve this
issue, I'm having this POP3SVC event id 1023 saying error 0x7da
processing some emails.

I disabled antivirus on Exchange and I still receive those 0x7da
errors.

I'm not able to reproduce the error (tried to create a meeting with
outlook 2007, invite a user who connects through POP, modified the
meeting and then receive it through POP but it didn't generate any
error message)

I read
http://groups.google.co.cr/group/microsoft.public.exchange.misc/browse_thread/thread/f0950092b5bc73ff/5a08ab300f0ad483?hl=es&lnk=st&q=0x7da+exchange+outlook+2007#5a08ab300f0ad483
but it doesn't say how to solve the problem.

Actually I have some users connecting to Exchange using Outlook (RPC
over HTTP) and some others using POP.

Exchange has installed SP2.

I see that 0x7da is related with the color management but I don't
understand why it keeps showing the error everytime SOME of the users
who connect to the exchange using POP check for new mail (as you may
imagine my log is full of this errors).

If you're going to post the same question to multiple newsgroups you should
post one message addressed to all of the newsgroups one post so that answers
will be posted to all the newsgroups.

Have you verified that logging isn't turned up on this service causing you
to get diagnostic messages?

I'm having the same problem here, Windows 2003 SP2, Exchange 2003 SP2. Mine
is happening on IMAP4SVC. It happens every time a particular user here checks
his email via IMAP.

I have tried everything as well, including disabling AV, and tried
everything I could find on this issue. Here is my error message:

======================
Event Type:    Error
Event Source:    IMAP4SVC
Event Category:    Content Engine
Event ID:    1023
Date:        10/29/2007
Time:        5:48:52 AM
User:        N/A
Computer:    CORE
Description:
Error 0x7da occurred while rendering message 0001-0000000ff2b2 for download

======================

The message number changes if the bad message is moved. I don't know how to
delete that message administratively either. The message number is not
"findable" in any way I know how.

I decoded the error too, and found 0x7da relates to some color or character
display junk.

The user is using the latest Thunderbird and he gets an RFC 822 error every
time he checks the mail folder with this message in there.

I do not have excessive logging enabled either.

This is a very sinister problem, I despise when error messages can't be
fixed, why isn't this in a KB already?

Logging is not turned up on that service.

Today I saw another exchange doing the same thing on IMAP4 connections.
