Remove SEND button in Outlook 2010

I’d like to disable the SEND button in Outlook 2010. REASON: I am using a product that adds another button to the ribbon and is a secure send. I want to remove the original SEND button so that a user can’t accidently hit the original SEND button. I only need to do this on 5 PCs, so I can do it step-by-step on each PC, (I think it might involve changing the default form) or if there is an exe or macro or VBA that I can run to “disable” and then one to “enable” that would be even better. Please reply with your thoughts on how to do this, and your offer.
