Change Account "Password Never Expires"

Change Account "Password Never Expires"

We have quite a few accounts with "Password Never Expires" checked.  I'd like to uncheck those.  Ideally I could set each OU to expire a week a part or two so everyone isn't getting prompted at the same time.  Or prompt at next login.  I can't seem to figure out how to change this setting either way in AD Manager.  Can this be done?  Thanks.
