I got an email through today confirming I have passed the Exchange 2010 PRO exam beta and have now achieved MCITP Enterprise Messaging Administrator 2010 certification. :D
The PRO exam is available from today and you can find out about it here, http://www.microsoft.com/learning/en/us/exam.aspx?ID=70-663.
If you haven't taken the TS yet find out about it here, http://www.microsoft.com/learning/en/us/exam.aspx?ID=70-662.
The Exchange 2010 certification hasn't appeared on the MCITP page just yet, http://www.microsoft.com/learning/en/us/certification/mcitp.aspx#tab2.
