How do I shut off "Stationary" settings using Group Policy

Could somebody tell me exactly where to find Stationary settings in Group Policy?  I am having trouble with Outlook 2007 on a Citrix Farm.  Whenever a user (let's call him "Bob") enables the "Mark my comments with" setting, everybody on that server gets [Bob] comments forced into their emails.  Then the first user to notice the problem has drill down and deselect "Tools\Options\Mail Format\Stationary and Fonts\Mark my comments with:"  More often it is the help desk who has to do it because the users don't usually know how to do that themselves.  
It appears that it's not letting the users save the setting "per-user" but rather "per-server."  I know that Office 2007 has some features that are not stored in HKCU, so I'm not at all surprised about this one.  I'm thinking that the easiest way to fix this right now is to disable the feature completely.

That's very cool and I'm learning a lot about writing my own policies from it . . . however it doesn't solve my problem.  What I'm trying to prevent is the users selecting "Tools > Options > Mail Format > Stationery and fonts > Mark my comments with".  The policy settings in the above thread have no effect on that (although I did try them just to make sure).  If I knew the registry hack to do what I wanted, I could probably modify the .ADM file in the other forum to make it work.  
Here is a registry hack. Not sure if it will give the results you are looking for but you can try it.

If that doesn't work try chaing the 11.0 to 12.0 and see if that helps.

This is the same registry hack (for the most part) as the previous one, and it doesn't work either.

This has not completely solved my problem, however I believe that I can build the policy I need from this and some other information that I have.  If/when I get the full policy built and tested I'll come back and post it here.  Thanks so much for your efforts.
