I have a new exchange 2010 server that I recently built but it is used to host many different organizations and domain names. I just noticed that the new 2010 OWA app allows viewing the default global address list when you click the address book icon. I need this to go away.
I have read articles already explaining how to use ADSI edit and Powershell to limit viewing of the GAL to each organizations OU, which I tested and does work. However, there are too many people to script this way.
Is there a way to flat out block the GAL from OWA completely? I don't want it searchable, viewable, or even noticeable in the Address Book that comes up when you click the icon.
The default GAL cannot be deleted and appears to have to properties. Can I suppress it permanently (for all existing and new AD accounts created)?
