Exchange 2003 support was added in Data Protection for Microsoft Exchange
version 5.2.1.
Here is a web page that shows the "Hardware and software requirements for
IBM Tivoli Storage Manager for Mail version 5.3.3":

I don't know why, but I always have the hardest time
finding the simplest information on IBM's web site.
What TDP for Exchange supports Exchange 2003? Any
besides 5.3?
Is there a simple (ha!) spreadsheet somewhere that
lays out requirements, prereqs, etc for this kind of thing?
