In my experience it is true that you cannot deploy Office 2007 through GPO. At least, not as a machine-deployed install. There are some hooks that may leave it available as either a click-to-install or semi-automatic install as a user-policy, but not through the old-fashioned GPO/msi deployment routine. I agree it is a huge annoyance at best, being that you cannot do a standard 'upgrade' nor manage an absolute upgrade per-machine (as it was originally deployed in our environment). I don't understand the reasoning behind their change. For us, we've just purchased licenses a few at a time for users who have asked for needed features in Office 2007. Then, installed manually from a share. On a positive note, for the most part the 'upgrades' have gone OK, properly upgrading Office 2003 to Office 2007, however I have had a couple machines decide to re-install the GPO-deployed Office 2003 when a user clicked on a particular office-type file creating a mess of the Office installation. M$ fights the community so hard for their own standards, then undermine themselves?
