Use either the OCSUmUtil tool or the Get-CsExumContact cmdlet to verify that Exchange UM contact objects have been removed from the legacy Office Communications Server 2007 R2 pool. OCSUmUtil is located in the following folder:

%Program Files%\Common Files\Lync Server 2010\Support\OcsUMUtil.exe

OCSUmUtil must be run from a user account that has:

• Membership in the RTCUniversalServerAdmins and RTCUniversalUserAdmins group (which includes rights to read Exchange Server Unified Messaging settings)
  
  
• Domain rights to create contact objects in the specified organizational unit (OU) container
  
  

For details about using the Get-CsExumContact cmdlet, see Get-CsExUmContact in the Lync Server Management Shell documentation.
