Exchange 2007 is designed only for 64-bit architecture running a 64-bit version of Windows Server. Many IT leaders will be reluctant to commit to such a major hardware and software upgrade. For those enterprises, Microsoft Hosted Exchange E-mail and Services (on-demand delivery of Exchange 2007) will be a more cost-effective method of migration.
This tool compares the total cost of ownership of Exchange 2007 under two different delivery models: on-demand (software-as-a-service) and on-premises (in-house). Specific coverage includes:
- A summary of new functionality offered in Exchange 2007.
- Prerequisites that must be in place before upgrading MS Exchange Server.
- An automated tool for calculating TCO under the two delivery models.
- A graphical comparison of the two TCO calculations. As IT leaders begin to position Exchange 2007 on the enterprise's communication roadmap, this tool will be a key component in the planning and decision-making process.
