This issue may occur if the Everyone group is not assigned the Create named properties in the information store permission to the CN=Configuration,DC=Domain, DC=com,CN=Services, CN=Microsoft Exchange,CN=Organization object in the Active Directory directory service.

To resolve this issue, assign the Create named properties in the information store permission to the Everyone group. To do so, follow these steps: Warning If you use the ADSI Edit snap-in, the LDP utility, or any other LDAP version 3 client, and you incorrectly modify the attributes of Active Directory objects, you can cause serious problems. These problems may require you to reinstall Microsoft Windows 2000 Server, Microsoft Windows Server 2003, Microsoft Exchange 2000 Server, Microsoft Exchange Server 2003, or both Windows and Exchange. Microsoft cannot guarantee that problems that occur if you incorrectly modify Active Directory object attributes can be solved. Modify these attributes at your own risk.

2. Expand Configuration Container, and then expand CN=Configuration, DC=Domain, DC=com.
