Outlook 2011 does not use Exchange Cached mode and directly connects to the Global Address Book (GAL) via LDAP connection.Outlook 2003 (and older)* clients get their OAB from a public folder, Outlook 2007 (and newer) clients can get their OAB from 'Web-based distribution' (basically form the website on the Exchange (or Exchange CAS) server.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 you are in Cached Exchange Mode and your connection status is Disconnected, Trying to Connect, or Offline, you can see only the information that is in the offline address book.
So there are three factors stopping you seeing that new user on the GAL (, however if that’s not an option, read on). Force your Outlook Client to Download the Offline Address book. Check that the OAB is getting distributed from the Exchange/CAS server. Note: Make sure the Generation Server is set to a server that exists, and it’s online.
Support for Outlook 2000 was dropped with Exchange 2007, Exchange 2010 only supports Outlook 2003 (post SP2). In the diagram below you can see this server is performing public folder AND web based distribution, this is probably because you ticked this box when you installed the product.

In order for some GAL entries to show up properly you may need to turn off Cached Exchange Mode.
This morning I was asked to update the Global Address List and Offline Address Book in an Exchange environment.
