I am in process completeing a migration of 2003 to 2007 exchange. This migration was part accomplished when i came on board. There are many accepted authorized domains. The default email policy was set but not applied. The default policy will chaneg all users and contacts to default domain email. the contacts and other users cannot have there email policies changed, the automatic update email address policy is checked on all users and contacts, The one company has 3 OUs with users of one domain i dont want updated. How to accomplish task? i know i can select each user and contact individually and manually uncheck that box. Is there another way? Several hundred users and contacts are affected?
