SYMPTOMS
Users cannot download offline address books in a Microsoft Exchange Server 2007 environment. As an administrator, you notice that the offline address book folders do not exist.

This problem occurs if the following conditions are true:
 * The Exchange 2007 environment contains more than one thousand offline address books.
 * You use Microsoft Solution for Hosted Messaging and Collaboration (HMC) version 4.0.



CAUSE
This problem occurs because the Microsoft Exchange Information Store service maintenance procedure marks the folders as unused if the folders are not found in the Active Directory directory service.

By default, the Microsoft Exchange Information Store service maintenance procedure deletes the folders after eight days. If there are more than one thousand offline address books in Active Directory, the Microsoft Exchange Information Store service maintenance procedure reads only the first one thousand offline address books. The rest of the offline address books are marked as unused.



RESOLUTION
To resolve this problem, install Update Rollup 4 for Exchange 2007. For more information about Update Rollup 4 for Exchange 2007, click the following article number to view the article in the Microsoft Knowledge Base:
