They do a terrible job of getting novice users started. In the first chapter they lecture about knowing objects inside and out, but really don't support any means of doing that short of reading the Appendices and memorizing them without any sense of context. Basically, you already need to have a VERY strong background in VBA / VBScripting for Windows applications. If you are not a HIGHLY proficient programmer/scripter who is merely looking to turn his/her focus onto how to apply those skills to this specific (and peculiar) environment, FIND ANOTHER BOOK.

I just recieved a copy of this title a couple of days ago and I thought I drop some lines here. It's a great book for those who want to learn more about Outlook forms, COM-addins, Outlook 2000 VBA and also how to access outside data within Outlook forms. It also covers useful hints that can't be accomplished with Outlook directly using other technologies like CDO etc.
