The trend towards moving from Exchange on-premise to Exchange Online and Office 365 continues to pick up speed with more migrations across all sizes of organizations. Office 365 has been called Microsoft’s fastest growing business ever, a statement that is particularly meaningful given the past success of the technology giant.

A look at the adoption numbers adds considerable credence to this statement. Over 50,000 organizations are moving to Office 365 each month, taking advantage of the shared infrastructure and technology services that make up the cloud collaboration service. While Office 365 encompasses a broad suite of capabilities, the number-one driver for organizations moving to Office 365 is email.
