How to hide someone's email address from global address list but display in custom address? In my side, our domain is a sub domain,there is a need for one person: hide his email address in global address list, but display in our sub domain address(a customed address). i can hide his email address in global address list by emc, but there is no experience to display in our sub domain address at the same time. who have experience of this matter please give me some advice. Thanks, Adsnowadsnow

I can't tell if you want to hide a certain address of a recipient from the address list, or hide the recipient itself because you seem to be using the term address interchangeably with recipient. The global address list is just that--it's global. If you want some objects to show up in some address lists but not in the global address list, then I believe you're going to have to hide the global address list and provide a custom address list that has everyone except the ones you want excluded. Please clarify your question if I'm not answering what you're asking.Ed Crowley MVP "There are seldom good technological solutions to behavioral problems."

yes,there is a person, who will be another domain user, I created a Temporary account and enabled the email box in my subdomain.we need this recipient display in our sub domain custom address but hide from global address list for some day his formal account will be create in his sub domain.His sub domain will be create in 2 or 3 weeks, then I will forward his email with accout of my sub domain to his new account for 1 or 2 months and then disable it. adsnow

Hi Adsnow, In Exchange 2010, we can create multiple GAL and display different users based on user group. But for a single person who has multiple email addresses, we can not choose to hide one address and display the other address. Your understanding would be appreciated.

You would have to create two separate accounts and assign one address to each.Ed Crowley MVP "There are seldom good technological solutions to behavioral problems."

Both of you are right,but the person only has one email address with his mail box.this address list in both global address list and our sub domain address(a customed address).I want to hide his address in global address list but keep in our sub domain address(a customed address). thanks for both of your quickly replys. adsnow adsnow

You can do the GAL segregation with Exchange 2010 sp2. The way it always worked is that users in the subdomain will not see the GAL but only their partitioned address list. So hiding the user from the default GAL is moot. http://blogs.technet.com/b/exchange/archive/2011/01/27/3411882.aspxJames Chong MCITP | EA | EMA; MCSE | M+, S+ Security+, Project+, ITIL msexchangetips.blogspot.com

the version of our server is exchange 2007 sp3,here is a sub domain no permission and right to modify the organization level settings . I found in your link "the ACL based GAL Segmentation ".Could you give me some infomation about "the ACL based GAL Segmentation "? adsnow

Follow this doc, what you have to do is when you create a new GAL you have to filter the recipients to be added to the new GAL then apply security restrictions. You can't filter based on the domain itself (only smtp address) so you have to create a new smtp accepted address for the other domains @subdomain1.company.com and apply this to your subdomain users. Than you can build a new GAL based on the smtp address filter.
