Microsoft, which beat out Google and IBM for the email contract, provides San Francisco with easy interoperability between its other products such as Word, Excel, SharePoint, and Azure. The email service will cost the city $78 per user per year, or $1.2 million for the first year. This is significantly cheaper for the city than having to pay for its own servers. When the system is fully deployed, in about a year, it will cost $1.7 million per year."
