Have a exchange 2007 hosted enviroment, ( yes I know not supported) but is working well. Some, not all my users can see the default GAL and in return are seeing other clients users.(not good)
I have verified that the each security group (each group has own security group) has a deny read on the default GAL. I keep removing the default GAL from the user attributes in AD show in address book setting but it keeps coming back.
Sorry my first post so if I missed some info please let me know.
Enviroment is a single windows 2008 standard server running exchange 2007 sp2
