In part he has a link to &nbsp;&quot;Configuring Virtual Organizations and Address List Segregation in Exchange 2007.&quot; &nbsp;<a href="http://technet.microsoft.com/en-us/exchange/bb936719.aspx" rel="ugc">http://technet.microsoft.com/en-us/exchange/bb936719.aspx</a><br />
Option1 sounds like the one I will use.<br />
I now have a problem when I ran this command<br />
Get-GlobalAddressList Default Global Address List&nbsp;| Add-ADPermission -User &quot;Authenticated Users&quot; -AccessRights GenericRead -ExtendedRights Open-Address-Book -Deny:$True<br />
My Default Global Address List disappeared. &nbsp;I'm hoping this is what is suppose to happen but now later on in the documentation were I am suppose to add a Security Group for all Hosted Groups I get this error message.<br />
Add-ADPermission : CN=Address Lists Container,CN=company,CN=Mi<wbr />crosoft Exchange,CN=Services,CN=Co<wbr />nfiguratio<wbr />n,DC=compa<wbr />ny,DC=loca<wbr />l was not found. Please make sure you have typed it correctly. At line:1 char:17 + Add-ADPermission &nbsp;&lt;&lt;&lt;&lt; -Identity &quot;CN=Address Lists Container,CN=company,CN=Mi<wbr />crosoft Exchange,CN=Services,CN=Co<wbr />nfiguratio<wbr />n,DC=compa<wbr />ny,DC=loca<wbr />l&quot; -User &quot;All Hosted Groups SG&quot; -AccessRights GenericRead -Deny<br />
I worried I have hosed my entire Exchange environment.<br />
Please Advise<br />
<br />
Thank You

<a href="http://technet.microsoft.com/en-us/exchange/bb936719.aspx" rel="ugc">http://technet.microsoft.com/en-us/exchange/bb936719.aspx</a>&nbsp;<br />
Over halfway down in the document it talks about<br />
Modify the msExchQueryBaseDN:<br />
$user = ([ADSI]&quot;LDAP://DC01:389/CN<wbr />=Test User1,ou= Fabrikam,ou=companies,dc=c<wbr />ontoso,dc=<wbr />com).psbase; $user.Properties[&quot;msExchQu<wbr />eryBaseDN&quot;<wbr />].Value = &quot;ou= Fabrikam,ou=companies,dc=c<wbr />ontoso,dc=<wbr />com&quot;; $user.CommitChanges();<br />
<br />
Can you tell me is the CN=Test User1 suppose to be a user or a Security Group the users are in?<br />
<br />
Thank you.

Restrict users from seeing a specific Address List
