Offline address book not updating on Outlook 2003 or 2007 client in Cache Mode from 2007 Server
Posted on 2007-11-29
We just upgraded our Exchange 2003 Server to Exchange 2007. When new users are added to the Exchange environment, they show-up in the client address book if they are in online mode but, not if they are in cached mode. We have tried to download the address book, set a registry key to control how the offline address book is updated to no avail. The only thing that seems to update the cached address book is if you delete the *.oab files from the client's computer and restart Outlook.
