Tired of waiting on the Internet? Ever wish you could study MAPI while you’re sitting on the beach? Well now you can! The Outlook 2007 MAPI Reference has been conveniently repackaged as a downloadable .chm file you can install on your laptop and take with you on the go. Enjoy!
[Edit] The problems with the download have been fixed. I was able to install on the machines where it failed before. Let me know if you still have problems installing it.
