Should you do the Ex2003? I don't know. I'm skipping it, going right to Ex2010. I figure that having a certification in the newest technology is enough and if you're experienced in the older version - as you obviously are, that should be more than enough.

Unless you work for a pure staff-aug firm, most of your Exchange consulting gigs will be migrations to later versions of Exchange. You may be migrating from Exchange 2003 or through Exchange 2003 since 2010 has no connectors to other mail systems like Notes or GroupWise. Take the 284 exam just to solidify your Exchange base skills. I administered for a few years before I took the exam and I still learned quite a bit studying for it. 285 won't help much (unless you want the MCSE:Messaging specialization) since there isn't much interest in 2003 design work these days. You should certainly take the 236 exam for 2007. We are still seeing a lot of interest in migrations to 2007 because some companies prefer to run more seasoned server applications. Besides, you may eventually lead a migration from 2007 to 2010 so it's good to know both versions. The 237 exam is easy and I felt the 238 exam was the best Exchange exam I have ever taken, if not the best Microsoft exam I have taken. Other companies skipped 2007 and went straight to 2010. Personally, I would choose 2010 over 2007 today, and most companies will get there eventually. I felt the 662 was a very easy Exchange exam, but I haven't taken the 663 yet. Taking an OCS exam will help your organization qualify for the Unified Messaging partner competency. It will also help if you are doing migrations from Notes to Exchange because you can handle an OCS deployment to replace the SameTime functionality. 2007 is your only real option right now - I haven't heard anything about the OCS 2010 beta exams, or really anything about the new OCS 2010 specs.
