Did you run the schema extension with /prepareAlldomains?

No i did not run Kindly help me how to do

Hi, Agree with LMurthy, you must run /preparealldomains to extend the Active directory schema. To do that you must run it from the installation media of exchange: Setup.com /preparealldomains Good luckBest Regards Don't forget to mark it as answer if it helps

Hi SDP, You can know more information about “/preparealldomains” from this document: Preparing your AD for Exchange 2007 SP1 (/PrepareDomain and /PrepareAllDomains) http://blogs.technet.com/b/gerod_serafin/archive/2008/01/11/preparing-your-ad-for-exchange-2007-sp1.aspx Thanks, Evan
