Exchange Server 2010 provides integrated email archiving capabilities that:
1. Allow organizations to meet compliance regulations by automatically moving emails older than a certain age to a separate archive mailbox while maintaining the same folder structure and search experience for users.
2. Simplify administration through familiar management tools that enable setting retention policies on folders or individual messages and placing litigation holds.
3. Reduce costs by providing a single infrastructure that supports archiving, retention, and discovery without requiring separate applications or user retraining.
