Update: I found one user that uses OWA exclusively and the message was not
marked as Junk in their mailbox, so this means the problem is with either
Outlook 2007 or the 2007 Junk filter updates.

Actually, I would suggest testing on a problematic user. If the automate
mail doesn't filter in OWA, but filter to Junk folder when the problematic
user launch the outlook. It would isolate the root cause to the outlook
client completely

Can you confirm whether the issue happens to all users?
Are there any users who don't filter the same automate mail that has been
filtered to the problematic users' Junk folder? If have, you can check if
there's any difference between the working machine and the problematic
machine, like the outlook version, and other third party software

I agree, since the OWA exclusive user does not have the issue, which makes
me conclude that the Outlook 2007 junk email updates are responsible for
classifying the message as junk and moving it into the Junk Email folder.

The issue occurs with all Outlook 2007 users that have not already added
the domain or email address to the safe senders list in Outlook 2007. I am
preparing to deploy the safe senders list via group policy to all domain
users, but have run into problems since the Outlook 2007 SP2 ADM template
does not include the necessary registry key
HKEY_CURRENT_USER\Software\Microsoft\Office\12.0\Outlook\Options\Mail
"JunkMailImportLists"=dword:00000001. Also once this key is added manually
and the GPO appears to run, there is no indication in the Outlook 2007 Safe
Sender user interface that the central list has been successfully merged
with the original users list.

GPO to append to Safe Senders -- need two extra registry keys

How did you add it manually? Do you upload the template into the GPO as
suggested by Mike Shen in the link?
Copy the custom template into a text file, and then name it as
OL2K7JunkMail.ADM. Use it on the GPO
