SYMPTOMS
After you restrict Search permissions in your Microsoft Exchange Server 5.5 site, when you regenerate the offline Address Book (OAB), you experience all the following symptoms:
 * Microsoft Outlook users can no longer download the OAB.
 * If you view the OAB Version 2 public folder in the Public Folder Resources container in Microsoft Exchange Administrator, you notice that it does not contain any entries.
 * You notice a new public folder that has a GUID as a display name in the Public Folder Resources container in Microsoft Exchange Administrator.

CAUSE
This problem occurs because when you restrict Search permissions in Exchange Server 5.5, the Exchange Server 5.5 offline Address Book generation goes into security mode. Because of this security mode-based offline Address Book generation, the offline Address Book is created in a folder that is named by using a GUID instead of being created in the OAB Version 2 folder as you expect.

Hotfix installation information
After you install this hotfix, you can use a registry entry to modify the default behavior in Exchange Server 5.5 so that the OAB is generated in the OAB Version 2 folder instead of in a folder that is named by using a GUID.Warning If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk.

To use the functionality that is provided by this hotfix, modify the registry on the Microsoft Exchange Server 5.5 computer. To do this, follow these steps:  On the Exchange Server 5.5 computer, start Registry Editor. To do this, click Start, click Run, type regedt32 in the Open box, and then click OK. Locate and then click the following registry subkey:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\MSExchangeDS\Parameters

 On the Edit menu, click Add Value. In the Value Name box, type OAB disable search control, click REG_DWORD in the Data Type list, and then click OK. In the Data box, type 1, and then click OK.</ol>

After you enable this registry value, OAB generation does not verify search control and creates the OAB in the OAB Version 2 folder.

Important If you use Exchange Server 5.5 to host other organizations, carefully consider the implications of this registry modification before you implement it in your organization.
