During the Microsoft Partner Academy BizTalk class I was working with Lesson 5 (BAM) of the online Microsoft BizTalk tutorials. Out of interest I started to follow the complete course from the beginning.

The tutorials guide you through most BizTalk aspect which a beginning BizTalker should know, in fact it covers almost everything I learned from my paid BizTalk course, but these tutorials are free!

So if you would like to get a hang of BizTalk, grab yourself a 120 day trial copy of BizTalk and download the tutorials.
