Remember, if you are looking at the Global Address List in Outlook then you are NOT looking at the Servers Global Address List*.
Or force Outlook to download the latest version of the offline address book.*Note: Disabling cached mode is not really a fix!After you restart the File Distribution Service on the CAS server, you should be getting the same files from the OAB generating server to the C:program files Microsoft Exchange Server V14Client Access OAB on the CAS server .You have set up Outlook Photos and added photos as you require, however the photos are not appearing in Microsoft Outlook 2010.The Global Address List (GAL) has not updated from Active Directory. To get the OAM to immediately generate run the following command: Update-Offline Addressbook “name of offline address book”.
You may encounter an issue stating that the System Attendant Service is not running or you do not have permission. Make sure you are running the Exchange Management Shell as Administrator and 2. *note* The Service is named “Microsoft Exchange System Attendant”.For public folder distribution ensure the public folder database is mounted, and at least one server holds a replica.Also in the properties of the mailbox database, your users are using, make sure it points to the correct public folder database.This is my issue: We are using Exchange 2010 and Outlook 2007.Last week we added a new conference room in Exchange.When I look up the conference room in the Global Address List, it doesn't show up. So as I understood from our Sys Admin, the oab files are generated on one server, and rely on the file replication service on the global catalog servers (we have 2 of them) to copy the oab files to each of the servers.
