Background: Company is transitioning from Exchange Server 2007 SP2 environment to Exchange Server 2010 SP2 Rollup 1. The company has purchased Exchange 2010 Enterprise CALs for all users. The company wants all mail to be retained for 7 years which the users cannot move, delete, or view in Outlook or OWA. The Exchange administrators are obviously supposed to have this privilege but no other users.
Question: Is it possible and if so how is it accomplished to configure Exchange 2010 archive mailboxes to not be visible by Outlook or OWA for non designated Exchange admins?
