∞ Introducing Google Message Continuity
Google Message Continuity works by replicating email accounts hosted on Microsoft Exchange Servers in the cloud, using Gmail, Calendar and Contacts. If the Microsoft Exchange Server fails, or requires scheduled maintenance or downtime, all you have to do is log into Gmail and continue regular, up-to-date email communication through Google. Since Gmail and Microsoft Exchange are constantly synchronized with each other, you can seamlessly switch from one email environment to the other.
Google is announcing this as a backup plan for your in house Exchange server, but it is an obvious solution to transition to Google Apps completely.
