Only 50% of organisations have made significant post-deployment savings using cloud-based e-mail, according to a study by MWD Advisors.
The Market Insight: Perceptions and reality: the truths of cloud email adoption report found that the reality of deployment does not always meet with expectations. In the survey of 56 organisations, 15% of respondents reported no cost reduction at all.
The survey highlighted a mismatch between the concerns organisations yet to deploy cloud e-mail have with the reality of the issues that cause the greatest problems in practice. The primary concerns or deterrents for those organisations that had not yet deployed cloud e-mail relate to the availability and reliability of the service (57%) and gaining assurances around security and privacy (52%).
Angela Ashenden, principal analyst and author of the survey and report, said: "Our survey tells us that organisations considering cloud e-mail deployment should be more aware of the integration challenges with existing on-premise systems such as LDAP directories, or HR and CRM applications; this is backed up by the detailed case studies we've also done."
Ashenden said cloud e-mail providers need to address the deployment concerns and offer guidance around deployment risks and best practices.
