Unified Communications Certificates Listing updated: August 11, 2008

Entrust Unified Communications Certificates (UCC) provide greater flexibility to support Microsoft Exchange Server 2007 without sacrificing security controls. Entrust UCCs secure and authenticate communication between mail servers (internally between the Exchange servers, and between Microsoft Exchange servers and other mail servers). Required for all but the most basic Exchange environments, Entrust UCCs allow administrators the ability to enable the new Auto Discover provisioning feature provided by Microsoft Office Outlook 2007 and Outlook Web Access through Microsoft Exchange Server.

Entrust Unified Communications Certificates can help reduce upfront and ongoing management costs by using a single certificate on multiple customer servers. This not only helps limit upfront certificate costs, but also means organizations are only required to manage and renew a single certificate over time.
