Since I don't use Outlook, I didn't really follow the discussion that carefully. Re-reading the discussion it seems that you don't get a rejection message all the time. Often what happens is that it points to your host. If you have mailhosts, it may not point to your host all the time thus alerting you to the fact that something is wrong with the parse. If it stops at another incorrect point, you may not notice that the parse is incorrect and that if you send the report, you will be reporting the wrong IP address.
Assumption is that deputies pay attention to the test message asking to be allowed to do quick reporting and deny quick reporting because you are using Outlook. I don't remember how VER works - whether you have to be approved or not. The parser, of course, cannot identify an Outlook spam submission since it works on the /attachment/. However, the headers of the email to which it is attached, possibly could be identified as coming from Outlook by X headers though no one found an example.
The official spamcop page is a little confusing about whether the add-on programs can still be used.

Outlook does not properly forward mail with the headers and message body intact. It is not possible to use SpamCop's email submission system with Outlook unless you use one of the below add-on programs or similar macro.

Email submission system
It is not possible to use the email submission system with Outlook. The add-on programs mentioned above will not work with Outlook. You must use the web form to submit spam if you use Outlook as your email client.
I don't understand why they did not delete 'unless you use one of the below add-on....' if they will not work. The only reason I can see is that they do still work on earlier versions, but not Outlook 2007. The alternative is, as Farelf suggested, that the add-ons no longer work with the new version of the parser. In which case, why did they retain mention of the add-ons at all? Why didn't they say, "Add-on programs were developed by spamcop users for previous versions of Outlook, but no longer work properly."
However, in Ellen's announcement, she also mentions that mailwasher or other add-on programs may allow you to forward spam. I don't know how mailwasher works, but apparently it captures the spam email before Outlook so actually you are forwarding from mailwasher (which doesn't mangle headers) rather than Outlook. Perhaps, other add-ons could work the same way, but not the ones developed earlier (which were revised in 2004 to work with a new spamcop parser version).
Is that '
what's missing'? If so, that answers both the question of 'Do Outlook users know that they may be submitting incorrect reports?' answer - no and the reason for the test message - to see if spamcop can identify an email from Outlook - the answer seems to be that, at this time, it will not since it only examines the attachment (which doesn't come from Outlook and Outlook doesn't add anything, just scrambles the header lines).
The person who edited the official spamcop page has 'loosed' a lot of questions even though a clear understanding may be lost. Hopefully, some of that 'loosed' valuable information that ISPs need will find its way home by a new add-on.
