Google has revealed its Message Continuity Service, a hosted continuity solution for on-premise e-mail servers. The offering synchronizes Microsoft Exchange 2003 and 2007 on-premise exchange servers with Google's Gmail service.
Matthew O'Connor, product manager for Google Enterprise, said in a blog post:
By synchronizing your on-premises accounts with Google's cloud, Google Message Continuity gives you access to your up-to-date email inboxes (through the Gmail interface) no matter what happens to your on-premises servers. And once your servers come back up after an outage, messages sent and received, plus message state changes (like deletions and folder assignments) that are recorded by Google Message Continuity during the outage, are then synchronized with your servers, allowing users to seamlessly transition from Microsoft Exchange to Gmail, then back to Microsoft Exchange.
Offered by Postini, Google's corporate e-mail service, Google Message Continuity costs $25 per year per user or $13 a year per user for current Postini customers, InformationWeek reports. The service also makes it easier for a company to transition to Google services. Rajen Sheth, group product manager for Google Apps, noted in a blog post:
Since Microsoft Exchange and Gmail are always in sync with one another, there's no need to migrate email data when eventually deploying Google Apps.
