Electronic messaging is mission critical, but remains vulnerable to a growing array of threats. Viruses, worms, denial-of-service attacks, spam, legal e-discovery and the need to satisfy a growing set of government regulations all make effective message management increasingly difficult.
Microsoft offers a range of solutions to assist companies in meeting complex e-mail compliance requirements, including hosted services for e-mail filtering, encryption, archiving and continuity assurance that help businesses communicate with confidence. Microsoft Exchange Hosted Services provide enterprise-class reliability for messaging security and management, actively ensuring the security, compliance and availability of electronic communications. EHS helps customers simplify the administration of their messaging environments and are easy to deploy, manage, and maintain. The hosted services model requires no hardware or software installation, minimizes up-front investment and provides a predictable payment schedule through a subscription-based service.
As a component of the Microsoft Exchange solution portfolio, Exchange Hosted Services provide a layer of protection features deployed across a global network of Internet data centers. The services create a security-enhanced message stream to and from your on-premise messaging infrastructure.
HOW IT WORKS
With just a simple mail exchange (MX) record configuration change, our services can be up and running quickly. There is no hardware to provision; no software to buy, install or configure; and no expensive training required for your IT staff.
Furthermore, there is no need for you to change or modify your existing e-mail infrastructure, or to even install and maintain any new hardware or software. The heart of Exchange Hosted Services is its distributed network of data centers located at key sites along the Internet backbone. Each data center contains fault-tolerant servers that are load-balanced from site to site and from server to server. In the unlikely event that one data center is unavailable, traffic can be easily routed to another data center, minimizing the chances of interruption to the service. In addition, Microsoft algorithms analyze and route message traffic between data centers to help ensure secure and timely delivery. With this highly available network Microsoft provides service level guarantees of 99.999% uptime.
