Page 14 Operational Efficiency Optimized for performance and scalability “The average corporate user generates and receives about 84 s per day which require about 10 MB of storage on a daily basis. And by 2008, s will require about 15.8 MB of space daily.” - Radicati Group, 2006 Simplified server routing Fast and accurate search Native 64-bit architecture  Superior performance  Improved storage efficiency 64-bit by the numbers 32-bit = 2 32 or 4 gigabytes of addressable memory 64-bit = 2 64 or 16 exabytes of addressable memory

Page 15 “There will be 1.4 billion mailboxes by the end of 2006 and that number will grow to 2.2 billion mailboxes in 2009, an average annual rate of 16%.” - Study from Radicati Group, 2005 Operational Efficiency Easier and more flexible deployment Modular setup based on server roles; smart default settings Automatic configuration with Outlook New web services enable rapid development

Page 16 “IT professionals spend up to 70 percent of their time maintaining existing systems.” - Accenture Study, 2004 Operational Efficiency Greater administrator productivity Improved, more intuitive management GUI Powerful command line shell supports automation and batching Exchange Management Shell Exchange Management Console

Page 18 Reduced TCO: MS IT Case Study Tape backups replaced by continuous replication, saving 5 million a year 64-bit technology and Exchange 2007 CCR feature enabled MS IT to lower storage costs by 50%, and still deliver a 10 fold increase in user’s quota 1,500 users moved on a weekend compared to taking a week at 200 users per night Cluster Continuous Replication allows us to maintain our high service level agreements on lower cost hardware, removes our dependency on expensive tape backups and eliminates the single point of failure. It’s availability based on software, not dependent on hardware.” – Kyryl Perederiy, Senior Systems Engineer, MS IT Source: Microsoft IT on Exchange Server 2007
