Let me respond to my own posting. Yes ADModify works with Exchange 2007!
Start ADModify. I used version 2.1:
Select Modify Attribute. Pick domain and DC. Click on arrow. In ADUC like interface, click on desried OU. Select all the users after they show-up in the right pan. Click next. Go to E-Mail Addresses tab; check and configure the box labeled 'Remove E-mail Address'.... like "smtp:*".
From the hub transport, you also need to modify the email address policy.

This course will introduce you to Ruby, as well as teach you about classes, methods, variables, data structures, loops, enumerable methods, and finishing touches.

After you change the email policy - you can right click on the policy and select apply to re-apply the policy.
I don't think email address policy will remove the addresses - in much the same way that recipient policy wouldn't in Exchange 2003. should be able to remove the addresses for you though.

Are you sure ADmodify would work? With Exchange 2007, email addresses are not part of User Properties in AD, even with Windows 2003.
