Custom Attribute

[Guest group policy]

Hi

When I create any user account we always have to mention user’s employ code

in exchange advance tab-> Custom attribute-> extentionAttribute1 in user

properties. After that when we check that user account properties in outlook

address book (GAL) it shows the employ code in EmpCode field. What is this

EmpCode field, is this field is created by the administrator or it is

default. If it is created by administrator, Please tell me how it is

possible. We are working on windows 2003 and exchange 2003.
