I don't think that is going to work... or at least last time I checked it wouldn't, but that was a couple versions ago. I don't think it could have changed in the newer versions because of how the Default Mail Client is handled.
I tried to get this working a while ago when the call came through customer support. I could not. Basically the problem is that the “Send to” is NOT an Outlook function. It is a Windows function of the Default Mail Handler. Whatever Mail client is used (Outlook, Outlook express, Thunderbird, etc.) registers its own MAPI dll. (which needs to be on the physical file system). Since Office 2007 runs in its own isolated virtual space, the Windows APIs cannot interact with it. While this may seem like a problem, it is actually by design. Sure there are both pro and con to how it works, but there is a reason for why it works that way. I had some url links to this info, but they pointed to the now dead Thinstall site.
Thanks for thr reply. Anybody else run into this problem? Or possibly a solution/workaround. I would think there would be a script you could run or symbolic link or something especially if the PC base is fairly standardized.
