Please Help Me Understand! Distribution Lists do no Appear in GAL

Hello Exchange Experts!

I have a strange issue with Distribution Lists and Address Lists.


Here's my setup:
Exchange 2010 - fully upgraded and clustered: CAS, DAG, Load Balanced, etc.

We use Address Book Policies to populate Address Lists and the OAB

Here's the scenario:
I have multiple clients hosted from an Exchange Cluster. To populate the GALs and ALs, I use a distribution list which is added to the user's Active Directory "Member Of" Profile. here's an example of the shell command I use to create the lists:

New-GlobalAddressList "Global Address List" -RecipientFilter {(MemberOfGroup -eq '$groupidentity') -and (IsMailboxEnabled -eq $true)}

My Issue:
Some GALs populate with Distribution Lists without any issue. However, there are a number of GALs that do not show any Distribution Lists, at all. I'm quite confused on what's going wrong, or if I'm doing the Address List population a valid way.


Thank you in advance for your assistance! I will be available to answer any questions you have!

New-GlobalAddress list will create an additional Global Address List. Now you have 2 Global Address List right.

New-GlobalAddressList "Global Address List" -RecipientFilter {(MemberOfGroup -eq '$groupidentity') -and (IsMailboxEnabled -eq $true)}

Open in new window

Your new GAL will consists of recipients with mailbox enabled and member of DL. The DL provided in $groupidentity. Based on my understanding, your new GAL will only contains mailbox not distribution.

Thanks for the reply. You're correct we have many GALs, one for each client we host. Both User and Distribution Lists are members of the DL from $groupidentity. Some of the GALs will show the users and DLs, but others will not...
