How do I separate Global Address Lists on Exchange 2010

We are hosting multiple domains on and Exchange 2010 server.  I need each domain to have its own Global Address List and not allow domains to see other domain lists.

Sorry - missed the last ping email for your comment.

So the Authenticated users are not inherited special permissions?  Is the include inheritable permissions from this parent's object parent ticked?

Address list segregation is not supportec yet on exhange 2010 so, unless you are using hosting version of exchange sp1, you cannot do it yet

Problems using Powershell and Active Directory?

Managing Active Directory does not always have to be complicated.  If you are spending more time trying instead of doing, then it's time to look at something else. For nearly 20 years, AD admins around the world have used one tool for day-to-day AD management: Hyena. Discover why

Tony1044 the link refer to exchange 2007,  exchange 2010 does not support address list segregation

Although not supported - I have used this article to segregate the Address Lists on my own 2010 server and know at least one other EE Exchange Genius who has done the same.

It is not a Supported Configuration at the moment as far as Microsoft is concerned, so if you walk down this route and get problems, Microsoft will not support you though.

But Alan did you try it with sp1, as far as I know you wont be able to update to sp1 or any future update

Alan HardistyCo-OwnerCommented:
I have updated to SP1 and so has the other EE Exchange Genius - mine is currently dragging down empty GAL's but the other Expert's isn't!  I have not had the time to look into this much yet - but know it can be done.

Installing SP1 after segregation can be achieved by a permission change.

Sorry - haven't tried it myself, but thought it worked, even on Exc 2010 pre SP1?

Others seem to be using it too:

I've followed these steps, but I'm still having issues.  Non administrative users can't read the new GAL's I created and the default GAL is still visible to everyone.

I followed them to the letter and it has worked for me and others I know who followed it.

You may have missed a step or two - it is a lengthy document.

I am working on building a test system to work on this issue.  As soon as I've completed my testing I'll let you know if I need further help.

FYI - My GAL's are now populated correctly!  Seems some twiddling with permissions took a while to apply - so with SP1 in place - all is happy : )

Ok, I've created a new server from scratch for testing.  I'm following the steps as outlined and this is the first problem I ran into. I of course changed the domain name to suit my environment.

 Procedure
To use the Exchange Management Shell to modify the security permissions on the Offline Address Lists Container for the Authenticated Users group
1.Run the following command:



$container = "CN=Offline Address Lists,CN=Address Lists Container,CN=First Organization,CN=Microsoft Exchange,CN=Services,CN=Configuration, DC=testdomain,DC=local"

remove-adpermission $container -user "NT AUTHORITY\Authenticated Users" -ExtendedRights 'ms-Exch-Download-OAB'

CN=Offline Address Lists,CN=Address Lists Container,CN=First Organization,CN=Microsoft Exchange,CN=Services,CN=Configur
ation, DC=testdomain,DC=local wasn't found. Please make sure you've typed it correctly.

If you open up ADSIEDIT.MSC (Start> Run> {type} adsiedit.msc {press enter}) on your test server (be very careful here - you can do lots of damage with ADSIEDIT).

Expand Configuration (if you can't see Configuration, right-click Default Naming Context and choose Settings, then choose Configuration)

Expand Services> Microsoft Exchange> First Organization (If that is what it is called)> Address Lists Container> Offline Address Lists.

Is the path you have expanded down exactly the same as the syntax you entered in Powershell (in reverse).  If not - correct it - try the command again and make a note of the correct path.

Close ADSIEDIT.

Yes, there was a problem with my path.  I corrected it and now have the following error.

[PS] C:\Windows\system32>$container = "CN=Default Offline Address Book,CN=Offline Address Lists,CN=Address Lists Contain

Alan HardistyCo-OwnerCommented:
I assume you pressed Y?

If so - the right is being inherited and thus can't be deleted without removing the inheritance first.

Looks like you may have missed a step.

I've copied and pasted the code step by step.. nothing has been missed.

Alan HardistyCo-OwnerCommented:
Okay - please fire up ADSIEDIT again, expand until the Offline Address Lists, then right-click and choose properties.  Click on the Security Tab.

What permissions does Authenticated Users have and are they inherited?

Computer-InnovationsAuthor Commented:
It says they are not inherited, but they also have no permissions assigned to them.
