SYMPTOMS
In the Microsoft Exchange Administrator program, when you attempt to import a Comma Separated Value (CSV) file that contains a Custom Attribute (N) field, the error message

Custom Attribute (N) is Unknown

is returned.



CAUSE
This problem may occur in some scenarios if you have renamed a custom attribute in the Exchange Administrator program and then try to use the new name of the field in a CSV file. Using the new name of the attribute in the CSV file will return an error referencing this new name.

Renaming the attribute to its original name may not solve the problem, based on which version of the Microsoft Exchange Administrator program you are using, and the revision level of the directory on the server to which you are importing.



WORKAROUND
Use the directory name of the custom attribute in your CSV import header instead of the display name.

The directory names of custom attributes are of the form

Extension-Attribute-n

where n is the number of the attribute.
