Hi, New Server 2003 X64 setup with Exchange 2007. None of the User are listed under GAL. I guess Exchange 2007 not talking to ADS?? If so, how to get it to talk?

If Exchange is not talking to Active Directory then you have a big problem because your Exchange server will stop working. I guess your problem is client related, offline addressbook downloads not working? Create an Exchange profile in outlook that does not use cached mode and verify if you can see the GAL Deli
