Some of my users are not showing up in the Global Address Book. I have determined it is because of the security of the users. When looking at the security for my users that are part of an OU, Exchange Enterprise Servers does not have any permissions listed. When I look at the security of the OU, Exchange Enterprise Servers have full control. On the Permissions tab of the user, I have put a check mark in front of "Inherit from parent the permission entries that apply to child objects" however the permissions from the OU don't apply to the users of that OU. Can anyone tell me what I am missing? Thanks, Brenda
