ADSI Edit is kindf complecated thing... it got lot of attributes that are difficult to understand. but i have checked values of both the fields in ADSI Edit, one that is visiable in ESM and the one that is not.. I have also compared the attributes of both the fields. i dont see any difference...
Anyways, i have used "ms-Exch-Extension-Attribute-1" for my custom values.. there are "ms-Exch-Extension-Attribute-1" to "ms-Exch-Extension-Attribute-15" attributes available in the schema, added by exchange server... using ADSI Edit i have changed the display name of these attributes. Everything works fine.. i am able to search contact on the basis of these attributes.... but i still wonder if we can add new attributes in AD Schema why cant we use these attributes in Exchange Server.
Now the next step, in Active Directory Users and Computers-->Find window these attributes are available as "Custom Attribute 1 to 15" . lets say my first field "ms-Exch-Extension-Attribute-1" is Officer ID, and if i search this Officer ID=2020 in exchange address book i find the right person. Now in AD when i use the find option, i dont see "ms-Exch-Extension-Attribute-1" or "Officer ID" but i see "Custom Attribute 1". ab i wana change that "Custom Attribute 1" label to "Officer ID"... man i dont find that "Custom Attribute 1" label anywhere in the world :)...
any suggestions </smile>
