2. Info-Tech Research Group2 Executive Summary Microsoft’s Exchange 2010 offers significant features and advantages over previous versions. Those considering e-mail 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

5. 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 2009. Microsoft’s partners no longer develop add- ons that support Exchange 2003. 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?

6. Info-Tech Research Group6 Summary Microsoft’s Exchange 2010 offers lower cost storage options, integrated e-mail archiving, new Outlook Web App and improved business continuity capabilities. E-mail archiving in Exchange 2010 is good enough for most organizations but fails to meet many regulatory compliance mandates. Info-Tech recommends: o Exchange 2007 IT shops wait for a future Exchange release. o Exchange 2003 IT shops migrate directly to Exchange 2010 as soon as possible. o IT shops with less than 500 mailboxes move to an on-demand solution. o IT shops with more than 2,000 mailboxes deploy on-premise. o IT shops between 500 – 2,000 mailboxes use Info-Tech’s TCO Calculator to select the best deployment method. 6 Info-Tech Research Group
