Rekans IT Pro, seperti kita ketahui bersama bahwa sebelum kita mendeploy Exchange 2007 pada suatu organisasi, terdapat langkah-langkah yang harus kita lakukan terlebih dahulu. Salah satunya adalah langkah Exchange 2007 Schema Preparation. Saya pernah mengalami masalah ketika melakukan langkah preparation ini.
Error nya dapat kita simak pada proses dibawah ini:
E2K7SP1EN64>setup /PrepareSchema
Welcome to Microsoft Exchange Server 2007 Unattended Setup
Preparing Exchange Setup
No server roles will be installed
Performing Microsoft Exchange Server Prerequisite Check
Organization Checks ......................... COMPLETED
The Active Directory schema will be upgraded if you continue. Verify that the organization is ready for Exchange 2007 by running the Exchange 2007 Readiness Check, which is part of the Exchange Best Practices Analyzer.

Add error on line 71: Unwilling To Perform
The server side error is "Schema update failed: An attribute with the same link identifier already exists."
4 entries modified successfully.
An error has occurred in the program
Proses terhenti pada entry ke 5, karena sudah terdapat atribut dengan link identifier yang sama.
Solusi nya adalah, dengan merubah linkID untuk atribut tersebut.
Langkah-langkahnya adalah:
- Copy source Exchange 2007 ke mesin (komputer/server) yang digunakan untuk melakukan proses preparation.
- Cari file PostExchange2003_schema44.ldf (bisa ditemukan di dua folder), gunakan notepad untuk mengedit.
- Cari string ms-Exch-Mobile-Mailbox-Policy-Link dan ubah entry linkID: dari 1058 menjadi 11900.
- Save perubahannya di kedua file yg ada.
- Lakukan kembali schema preparation.
Apabila masih timbul error yang sama untuk entry yg lain di Active Directory (misalkan ms-Exch-Mobile-Mailbox-Policy-Link-BL), ubah saja linkID-nya menjadi 11901.
Setelah proses Schema Preparation berhasil, sebaiknya replikasikan dahulu perubahan ke seluruh Domain Controller yang ada, baru lanjutkan ke langkah selanjutnya (PrepareAD).
Terimakasih dan Semoga Bermanfaat, :)
