We have several legacy DDGs that were migrated into Exch 2007 They are based off of LDAP filters and have no value for recipient filter. To create a new DDG in exchange 2007, im trying to create based on LdapRecipientFilter, the only way i found to do this is to set the RecipientFilter {(LdapRecipientFilter eq "ldapfilter")} unfortunately this does not seem to work properly. I know that the RecipientFilter uses opath. My issue lies in that there are attributes that opath doesnt understand. Can Opath work with all attributes in our AD Schema? we have attributes "employeeStatus" in the objectClass for Users. How can i use such attributes in OPath? Am i just not writing the filter correct or can i not use these attributes?

it seems that i found some answers in the following http://social.technet.microsoft.com/Forums/en-US/exchangesvrgeneral/thread/95c8bf21-0749-4d2b-83f7-dba3d013e0ab/ i understand the switch to opath, but it seems like you should be able to get to these attributes in Opath
