XADM: Can't Import Nested Container Recipients into DL

The information in this article applies to:

• Microsoft Exchange Server versions 4.0 and 5.0

SYMPTOMS

If you use the directory import process to create distribution lists (DLs), you may encounter a problem if you use recipients from sub-containers to populate the DLs. The import process completes without any errors, but the DL does not work properly.

STATUS

Microsoft has confirmed this to be a problem in Microsoft Exchange Server versions 4.0 and 5.0. We are researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available.

MORE INFORMATION

If you use the directory import process to create distribution lists, you have to make sure to use the correct distinguished name (DN) in the Members column of the Import file. If you have recipients in sub-containers, but you do not include both the top-level container and the sub-container in the distinguished name for recipients in sub-containers, the import will complete with no errors, but the distribution list will not work properly.

For example, say you have the recipient container "Recipients" and a sub- container of "Recipients" called "Other". The "Other" sub-container contains non-Exchange recipients.

You then create an import file in order to create a distribution list to send to some of the "Other" recipients. Call these "User1" and "User2". The distribution list is called "Users".

The following mock import file shows the incorrect way to create the import file for this example:

   Obj-Class Display Name Alias Name Directory Name Members
   --------- ------------ ---------- -------------- -------
   DL        Users        Users      Users          Other/cn=User1
   DL        Users        Users      Users          Other/cn=User2

Here is the same import file with the correct information in it for this example:

   Obj-Class Display Name Alias Name Directory Name Members
   --------- ------------ ---------- -------------- -------
   DL        Users        Users      Users
   Recipients/cn=Other/cn=User1
   DL        Users        Users      Users
   Recipients/cn=Other/cn=User2

NOTE: If you have already created a faulty distribution list, you will need to use the Overwrite option when re-importing the list with the correct format, or you can delete the distribution list and re-import it using the correct format. Using the "Overwrite" option may not work in the desired fashion depending on how your import file is formatted.
