I have a global address list that contains various external contacts, i.e. email addresses that do not belong to our company. I would like to hide these contacts from displaying in the GAL. How can I achieve this other than clicking on the contacts one by one and select "hide from gloabl address list" ? I am running Exchange2007 on a Windows 2003 Active Directory Domain. regards Yong Chee Wai

Do you want to hide all contact objects from the GAL? If so you can use the following command via the Exchange 2007 management shell. Get-MailContact | Set-MailContact -HiddenFromAddressListsEnabled $True This command will work on all existing contact objects. You will needto set the HiddenFromAddressListEnabled attribute to $true as each new contact object is created. Set-MailContact <alias> -HiddenFromAddressListsEnabled $True --Nick

You could also use ADModify.NET to make a bulk change in AD. http://www.gotdotnet.com/workspaces/workspace.aspx?id=f5cbbfa9-e46b-4a7a-8ed8-3e44523f32e2 Here's a short tutorial on how to use it: http://www.activedir.org/article.aspx?aid=130 Tony
