The nominated offline address book server does not exist in the organization
[This topic is intended to address a specific issue called out by the Exchange Server Analyzer Tool. You should apply it only to systems that have had the Exchange Server Analyzer Tool run against them and are experiencing that specific issue. The Exchange Server Analyzer Tool, available as a free download, remotely collects configuration data from each server in the topology and automatically analyzes the data. The resulting report details important configuration issues, potential problems, and nondefault product settings. By following these recommendations, you can achieve better performance, scalability, reliability, and uptime. For more information about the tool or to download the latest versions, see "Microsoft Exchange Analyzers" at http://go.microsoft.com/fwlink/?linkid=34707.]

The Microsoft® Exchange Server Analyzer Tool queries the Active Directory® directory service to determine the value for the offLineABServer attribute of the offline address book configuration object. The offLineABServer attribute is a single-valued distinguished name attribute that stores the distinguished name of the Exchange Server computer that is responsible for generating an offline address book.
The Exchange Server Analyzer also examines the value for the distinguishedName attribute of Exchange Server objects in Active Directory.
If the Exchange Server Analyzer finds the server listed in the offLineABServer attribute does not match the found distinguishedName attributes of Exchange Server objects, and that the offLineABServer attribute does not contain the string, DEL:, an error is displayed.
For each offline address book, Exchange generates and stores the offline address book files in a set of public folders on a specified server. If you see this message, it means that the server specified in the offline address list object does not exist. This situation may occur if the old offline address book server has been decommissioned or incorrectly removed from the topology. Exchange will not generate the offline address book until you specify a new server.
To correct this error in Exchange 2000 Server and Exchange Server 2003
In Exchange System Manager, under Recipients, click Offline Address Lists. In the right pane, right-click Default Offline Address List (or any other offline address list that produces this message), and then click Properties.
On the General tab, under Offline address list server, click Browse, and then click the server you want to use.
To correct this warning for Exchange Server 2007
Open the Exchange Management Console.
Expand Microsoft Exchange, expand Organization Configuration, and then select Mailbox.
In the results pane, click the Offline Address Book tab.
On the Offline Address Book tab, select "Default Offline Address Book". In the action pane, Click Move to start the Move Offline Address Book wizard. This wizard allows you to move OAB generation to a different server. It will also copy the existing OAB files to the specified server.
To use the Exchange Management Shell to set the server that will host Offline Address Book generation
Run the following command:
Move-OfflineAddressBook -Identity <OAB> -Server <Server>
Where: <OAB> is the distinguished name (DN), Domain\Account name, or GUID of the OAB and <Server> specifies the Exchange server on which to perform the selected operation.
For example, to move OAB generation to the SERVER01., you would enter:
Move-OfflineAddressBook -Identity "My OAB" -Server "Server1"
