A mailbox is not shown in certain address lists after you run certain commands on an Exchange Server 2007 mailbox

Consider the following scenario. You add the showInAddressBook attribute manually to a Microsoft Exchange Server 2007 mailbox. You do this so that the mailbox can show in certain address lists. You run certain commands on the mailbox, such as the Set-Mailbox command, or the Move-Mailbox command. In this scenario, the mailbox is not shown in the address lists.

This issue occurs because the address lists entries are removed incorrectly from the showInAddressBook�attribute in the Active Directory directory service.�

To resolve this issue, install the following update rollup: After you apply this update, create the following registry subkey on the Exchange Server 2007�server:

Path: Name: DisableALUpdate
Type: REG_DWORD
Data:� 1

Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.

You can use Active Directory Service Interfaces Editor (ADSI�Edit) to copy the�distinguishedName attribute of the address lists to the showInAddressBook attribute of the mailbox in Active Directory.
