Import External Contacts into separate OU

[AmytDev]

Please help.
I am trying to import external contacts into a new OU that I created in
Active Directory. The goal is to have these contacts available in Exchange.
I used CSVDE to export a contact that I created in that OU to mirror.
Unfortunately, the CSVDE import was not successful. The CSV file contained
these fields
(DN, objectClass, cn, sn, givenName, distinguishedName, instanceType,
displayName, targetAddress, mailNickname, name, objectCategory, mail,
showInAddressBook, physicalDeliveryOfficeName, telephoneNumber, department,
company)
Here's an example contact:
(CN=Angela He,CN=Users,DC=xicom,DC=local
contact
Angela He
He
Angela
CN=Angela He,OU=Radyne,DC=xicom,DC=local
4
Angela He
SMTP:[email protected] AngelaHe
Angela He
CN=He,CN=Schema,CN=Configuration,DC=xicom,DC=local
(e-mail address removed)
CN=Radyne,CN=All Address Lists,CN=Address Lists Container,CN=Xicom
Technology,CN=Microsoft
Exchange,CN=Services,CN=Configuration,DC=xicom,DC=local;CN=Default Global
Address List,CN=All Global Address Lists,CN=Address Lists Container,CN=Xicom
Technology,CN=Microsoft
Exchange,CN=Services,CN=Configuration,DC=xicom,DC=local;CN=All
Contacts,CN=All Address Lists,CN=Address Lists Container,CN=Xicom
