So there are three factors stopping you seeing that new user on the GAL (, however if that’s not an option, read on).
Support for Outlook 2000 was dropped with Exchange 2007, Exchange 2010 only supports Outlook 2003 (post SP2).
These are most likely users that have only recently been added…because the minute that Exchange does it’s standard maintenance window, it will most likely update.But what if, like me, you need to have it update right away due to something like a Black Berry server?Through trial and error, I’ve found out WHY the user is not put into the Global Address List right away and how you can force it there. For Users where Outlook is in Cache mode, They got to have their Outlook Address book Updated ,when they can access the latest Address book while they go offline.If Outlook is left running constantly in Cached Exchange Mode, it updates the Offline Address Book automatically about once a day, depending on Address Book updates on the server running Exchange. If using Outlook, query the GAL directly, or download the latest OAB. Before you do anything send the user you created a 'Test Email' from your own account.
