The New York City Department of Information Technology and Telecommunications (DoITT) provides IT services for more than 65 government agencies. The agencies previously used a variety of messaging systems, including IBM Lotus Notes, Novell GroupWise, and Netscape. Employees found it difficult and time-consuming to communicate with workers in other departments. And because many of the agencies lacked the funds and expertise to manage the systems themselves, DoITT spent a lot of time providing support. DoITT decided to migrate the agencies to a centralized system based on Microsoft Exchange Server 2003 and Microsoft Windows Server 2003. Twenty-five agencies currently use the solution, which has simplified IT operations and improved productivity. The agencies have also reduced the number of mailbox server computers from 45 to 4 and lowered IT costs by 67 percent.
