That would require writing and deploying an Outlook add-in or maybe some script, and even then the user could add it back in unless you block toolbar customization completely. Disabling it with GPO is your best approach.

I'm trying to hide the send/Receive button in the standard toolbar for
Outlook 2003. I've managed to disable it through GPO - but I need it to be
either hidden or removed from the toolbar.
Once I've worked out how to do this, I need to do it to about 400 PC's on a
network - so doing it manually on each PC isn't really an option.
If anyone can offer any suggestions, I would be eternally grateful.
Cheers,
Aaron
