Since July 1st Microsoft Dynamics aka MBS changed the requirements for CRM Master Certifications. Have a look here:

If you have partner access you can also have a look here:

Maybe you are a MBS CRM Master and don't know it yet. :-)

Now you don't need to have the Exchange Certification anymore to get the MBS Master for CRM Installation and Configuration. For me this means that I received my third MBS Master CRM Certification, which was confirmed by MBS a few days ago. Since I already have the MBS Master for CRM Application and Development, this means I have 'em all. :-)
