One more exam to go to complete the track for achieving the MCITP Enterprise Messaging Administrator exam track based on Exchange 2007.
You need to pass the following exams:
Prerequisite MCTS certification
Exam 70-236: TS: Exchange Server 2007, Configuring
Professional Series exams
Exam 70-237: PRO: Designing Messaging Solutions with Microsoft Exchange Server 2007
Exam 70-238: PRO: Deploying Messaging Solutions with Microsoft Exchange Server 2007
I only need to find time to prepare for the 70-238 exam. Concerning the other exams I can tell you that the 70-236 exam has a lot of questions regarding the powershell scripting for Exchange and the 70-239 exam is all about where to put which Exchange roles.
