Creating application object
I don't recall that there is an existing button wizard to do what you want, so you are just about 99.9% sure to need to work in VBA to build the message body and mail distribution list. The good news, if you are using Outlook, is that Outlook help has sample code on how to do that. The bad news would be if you were not using Outlook.
