You can disable any menu or toolbar command, such as Reply to All, by
using a Group Policy Object. The article at
http://office.microsoft.com/en-us/as...402401033.aspx
explains how; look at the section on "Disabling menu items and
command bar buttons."

If you don't want to write your own code to recurse the
Explorer.CommandBars
and Inspector.CommandBars collections to get the IDs that you need to
be able to disable certain toolbar and menu commands, you can use the
Outlook Spy tool from http://www.dimastr.com. I also have a complete
list in the appendices to my "Configuring Outlook 2003" book (see
signature).

More trouble than _I'd_ ever want to go through.
