Microsoft Exchange Hosted Services

A set of four distinct hosted services: Hosted Filtering, which helps organizations protect themselves from e-mail-borne malware; Hosted Archive, which helps them satisfy retention requirements for compliance; Hosted Encryption, which helps them encrypt data to preserve confidentiality; and Hosted Continuity, which helps them preserve access to e-mail during and after emergency situations. These services integrate with any on-premise Exchange servers that are managed in-house or Hosted Exchange e-mail services that are offered through service providers. [Exchange 2007]
