One of the main reason is the excellent level of expertise SMS has with regards to MS Exchange. This is backed up by 24/7 support which made a 200% increase of users easily manageable with little impact on internal IT resources. Also the integration with their Postini Spam filtering improved the battery life of mobile users dramatically as it cuts out all the spam before it hits the email server. So all in all, SMS is providing a great and cost-efficient service with a high level of flexibility.
From a user point of view the main benefit is the high level of flexibility with regards to mobile integration. From a financial point of view a hosted version was highly attractive as we can add and remove new users as and when it is required always knowing the cost involved.
