An organization I am working with wishes to set up a full copy of all email sent or received thru it's Exchange 2010 server for compliance and litigation purposes. It does not wish to have the users interact with the archive in any way. The goal is to keep a copy of each email as it is sent, before it gets to the recipient, and to keep a copy of each email before it is delivered to the staff, so there is no question about any email that has ever been sent or received. These archives need only be searchable/viewable by the domain administrator. Is this feature something that can be set up from within the Exchange environment, or is a third-party software required? What are the basic steps to do so?
