Essential Outlook 2003 document

One of the Outlook program managers just answered one of my questions with some info from an excellent new document that gives all kinds of details about how the client experience has been improved in Outlook 2003.  Curious about how RPC compression works, or what “buffer packing” is?  Do you want to know when Outlook selects “header only” vs “full item” download?  If your job is to deploy Outlook, or you just are curious about the answers to these questions, you need to read this document:

(PS: the link speed threshold is 128 kbps for determining to download full item or not, and it's as reported by Windows, so if you're using ethernet behind a dial-up modem, it will think you have a link of 10 Mbps)
