I didn't see any responses mention setting an automatic rebuild of the offline address book. If your system is not updating, it could be set to "Never" with the expectation that rebuilds would always be done manually. In Exchange 2003, here's how to check this: * Open the Exchange System Manager * Open Recipients / Offline Address Lists * Right-Click on "Default Offline Address list" o To manually force a rebuild right now, click on Rebuild / yes o To check the settings for the automatic rebuild, click on Properties - Look at the "update interval" - Use the drop down to select a predefined time. Never is one of the choices. - Or click on customize. For example, I skip the weekend and rebuild M-F once each day. - Ummm... don't run it too often because it does increase the load on your server and clients -- which folks may notice. ;^) Anyhow, that's what I do to speed up distributing changes to the offline address book.

The subject pretty much says it all. Last week, I removed a user from a distribution group; However as of today, most of my clients are still showing that person as being part of the list. If I manually redownload the offline address book on each client, the change shows up. Is there a GPO or something that controls the frequency of address book updates?
