And there is Microsoft Exchange Hosted Archive, which is available now, and can be summarized as "a centralized, easily accessible, and multi-functioning e-mail and IM repository to assist organizations manage increasingly complex retention, compliance, e-discovery, and regulatory requirements" (as taken from the MsOnline site).
