Info-Tech Research Group2 Executive Summary Microsoft’s Exchange 2010 offers significant features and advantages over previous versions. Those considering archiving will find Exchange 2010’s solution is good enough for most organizations but fails to meet many regulatory compliance mandates. Given migration cost and effort, Info-Tech recommends that clients currently running Exchange 2007 wait for a future release. For those organizations running Exchange 2003, Info-Tech recommends skipping Exchange 2007 and migrating to Exchange 2010 as soon as possible. There are three migration paths for these organizations – migrating to a traditional on- premise solution, an on-demand solution, or a hosted solution. 2 Info-Tech Research Group

Info-Tech Research Group5 Enterprises running Exchange 2003 on-premise with more than 2,000 mailboxes should upgrade to Exchange 2010 on- premise. Mainstream support for Exchange 2003 ended in April Microsoft’s partners no longer develop add- ons that support Exchange Exchange 2010 offers much greater functionality, improved availability options, and tighter integration with other Microsoft products. Capability exists to enable a hybrid deployment – allowing users to connect to on-premise servers when on the corporate network and an on-demand solution when travelling. The bandwidth demand that 2,000+ users place on a business’ WAN and router are too great to justify the speed and cost required to support a hosted Exchange environment. Large organizations typically have the resources required to complete the migration without external support. Exchange 2010 allows mobile users to connect directly to the server without requiring a connection to the corporate network. 5 Info-Tech Research Group Why should you upgrade? Why should you move to on-demand?
