I have a new Exchange 2007 server installed that was migrated from an exchange 2000. Everything is working fine except for 1 issue. The Domain comntroller is sitting on a 2003 server as well as the GC. When we add a new mailbox using the exchange 2007 managment console the new user will show up in the Global catalog as long as you log into outlook web access but the Outlook clients on the network do not see the new users. How do I force the clients on the network to update their global catalog?
