Do you mean that you want block certain users from OWA or do you want to block everyone's access to OWA when they are outside the network?
Just don't put OWA in your external DNS, and don't add an external URL for it in EMC.

You could also create a custom login page that verifies a group membership for external access.  I am not exactly sure how to do this, but in the Remote Web Workplace portion of Small Business Server, they have a login page for the RWW.  From there you can click on a link to view your email.  This opens OWA in a separate window without having to login again.  I have always suspected that the first login page does a Windows integrated authentication/login and that this authentication is passed to the new window to authenticate automatically with OWA, but I have never tested this.  The only problem with this approach is that OWA will still be published to all external users and if they can find the regular login page, they can just use that.
Ok, Is it posible to use TMG to control this ?
If Yes
How can i do that
