Hello, I currently have a default GAL and another Address list. I would like to have this secondary address list setup so that only certain people can see its contacts. I plan on having a separate OU with contacts that would feed this address list, so far I have been able to hide it with a 'This bookmark is not valid.' error, which is acceptable. However I would like to make sure that the contacts I place in this OU do not show up in the default GAL, or any others for that matter. Please advise. Thanks. This is Exchange 2007 with Office 2007 clients. -Andy

Hi Andy, What you want to do is known as GAL segregation. It is supported in Exchange 2007 SP1, but NOT recommended. Just for your reference: Exchange 2003 / 2007 Address List Segregation Document - Updates!! http://blogs.msdn.com/b/dgoldman/archive/2008/02/17/exchange-2007-address-list-segregation-document-updates.aspx White Paper: Configuring Virtual Organizations and Address List Segregation in Exchange 2007 http://technet.microsoft.com/en-us/library/bb936719(EXCHG.80).aspx?ppud=4 Hope it is helpful.Best Regards Fiona Liao E: v-fiolia@microsoft.com

I appreciate the answer, I did see that but am not too anxious to try that. Is there a way to only allow read access to a group on an OU that contains these contacts? And they will only show up to the people that are a part of that group. My lab environment is down so I cannot test this. -Andy

Hi Andy, If you read the article you may notice that the GAL segregation is actially Permission segregation--based on OU. From my research, the similar function you are looking for is expected to be realeased in Exchang 2010 SP2.
