Offline address book server is running on a front-end server
[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.

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 queries the Exchange_Server Microsoft Windows® Management Instrumentation (WMI) class to determine the value of the IsFrontEndServer key for the Exchange server. If the value for the IsFrontEndServer key is True, the Exchange server is acting as a front-end server.
If the Exchange Server Analyzer determines that a designated offline address book server is also a front-end server, the Exchange Server Analyzer displays an error message.
This error indicates that the nominated Exchange server for generating offline address books is a front-end server. If the designated offline address book server is also a front-end server, offline address book generation will fail. A new server should be nominated for this task. When a server running Microsoft Exchange 2000 Server that uses Service Pack 2 or later is designated as a front-end server, the following services no longer run:
Offline Address List Generation
Recipient Update Service
Free and Busy Tasks
Mailbox Cleanup Agent
Exchange Event Service
Site Replication Service (SRS)
Front-end servers are designed to handle incoming client requests from Microsoft Office Outlook® Web Access, POP3, IMAP4, Exchange ActiveSync, Outlook Mobile Access, and Outlook clients that are configured to use RPC over HTTP. Front-end servers are also sometimes used to relay SMTP messages to internal Exchange servers.
To resolve this problem, it is recommended that you designate a back-end Exchange server as the offline address book server.
To correct this error
Open Exchange System Manager
Under Recipients, click Offline Address Lists.
In the right pane, right-click Default Offline Address List and then click Properties.
Use the same procedure for any other offline address list that produces this message.
On the General tab, under Offline address list server, click Browse, and then click the back-end Exchange server that you want to use.
