I am actually in the process of preparing for this myself. &nbsp;You will need to first upgrade to 2010 exchange from 2003. &nbsp;You could do 2007 but I recommend 2010. &nbsp;You will also need to be aware that 2003 outlook will not work PERIOD with 2013 exchange. &nbsp;I can provide some in-depth steps once I get home as I have a write-up from start to finish i have been working on for my blog.
