Exchange 2007 address policies behave as expected (unlike 2003)

This article over at the Exchange Team Blog describes how Exchange 2007 Email Address Policies (EAP) work. This is the replacement for Exchange 2000/2003 Recipient Policies and the way that the Recipient Update Service worked (or rather, did not).

Essentially, when you make policy changes in 2007, they get applied. This is what you would want out of a policy, hence the name. If accounts fall in or out of scope, their address list changes. If you change the primary address for a policy, it gets updated. You can still exempt accounts individually from being affected through ADUC (or use a script), but basically, it now does what it says on the tin.
