Hi all,We have a single Windows 2003 AD and right now have the following:-one single Default Global Address book We want to create a Global Address book for a separate department, say ABC, so that:- users using the Default GAL cannot see the users that are members of the ABC department- ABC cannot see the Default GALI have configured permissions so that ABC cannot see the default GAL only their own GAL, but the ABC users still show in the Default GAL. Anyway to change this?

See below Technet articles Below articles wouldexplain you to configure GAL segregation in Exchange 2003.

Actually address list segregation in pure Exchange 2003 is not supported by Microsoft so I don't recommend configuring it. If you really want it then you may need to go for Exchange 2007 or Exchange HMC...
