Exchange 2013 dynamic distribution lists are not showing any members in the GAL. I've tried the old trick of sending an email to the group, which I've done and have confirmed a member mailbox receives the email...still no go.

When I run: 

$members = Get-DynamicDistributionGroup -Identity "dynamicgroupname"
Get-Recipient -RecipientPreviewFilter $members.RecipientFilter 

I get all members of ALL dynamic distribution groups, not just the one I list in quotes after -identity.

Most of the searches I've done return information only for Exchange 2003, 2007 and 2010, but not 2013. 

Any help in figuring this out would be much appreciated. Thanks!

We use query-based dynamic distribution groups.  When I need to see who's in the DL, I use the following shell commands:

$Group = Get-DynamicDistributionGroup -Identity <DL name>

followed by:

Get-Recipient -Filter $Group.RecipientFilter

This will output data like:

Name                          RecipientType

User A                         UserMailbox

User B                         UserMailbox

As for viewing member of the DL in the GAL, I just looked using my Outlook and if I look at the properties of the DL through the GAL, I do not see who the members are. Not sure if this is the norm or a bug, but there is no "Members" tab, just a "Member Of" tab in the properties window.

Hi,

Members of Dynamic Distribution Lists don't show in GAL, its by default.

I run your command in lab, it works as expected. So, please restart EMS to create a new session to Exchange and make sure the dynamic group name. Then retry this command to take a test.

If this doesn't work, please run this command to check how many results it will return.

Get-DynamicDistributionGroup -Identity "dynamicgroupname"

Best Regards.
