Few businesses can function without email. Email provides a critical co-ordination tool during an outage, But the cost and complexity of providing true email continuity means that many businesses do not have adequate plans in place. Continuity and archiving services may prove more cost effective for email than high availability clustering, especially when considered in the light of continued governance, risk mitigation and compliance.

The intended audience for this whitepaper includes those concerned with creating or implementing email management strategies, as well as managers with responsibility for business continuity processes. The paper looks at the general approaches available to ensure email continuity from a high level and the implications of deploying each strategy on infrastructure, budget, people and resilience.
