I’ve recently come across a problem where, For Exchange 2003 and 2007 co-existence environment, When an mail-enabled object is created, the x:400 address will not be stamped.
This would result in an NDR’s with the recipient name “BsB57FD40C9308F7479BF159E9F227E5DD_
cn=E5D7F3DC762455418BB3D96C1B7C13BC@domain.edu”
Reason:
This would happen because of mission X:400 address
Fix:
- The Exchange 2003 RUS is responsible to update the object attributes in a co-exist Environment.
- The Recipient Update Service has three System Policies that are installed by default when you install Exchange 2003. They are “Mail Enable Recipient”, “Mailbox Enable User” and “Hidden DL membership”.
- If the recipient update service identifies than a new entry was added (or modified), and it does have the mailNickname to be considered mail-enabled. Therefore, by default, the purportedsearch attribute should be below:
(|(&(objectCategory=person)(objectClass=user)(mailnickname=*)
(targetAddress=*))(&(objectCategory=person)(objectClass=contact)
(mailnickname=*)(targetAddress=*))(&(objectCategory=group)
(mailnickname=*))(&(objectCategory=publicFolder)(mailnickname=*)))
- You can locate the “Mail Enable Recipient” object by using Adsiedit.msc tool:
CN=Mail Enable Recipient, CN=System Policies, CN=ORG_NAME, CN=Microsoft Exchange, CN=Services, CN=Configuration, DC=DOMAIN_NAME,DC=com
- The user, contact and public folder object which have mailnickname and targetaddress (not for public folder) attributes.
