Another option is is using ADUC custom query,
Active Directory Users and computers > Right-Click the folder Saved Queries and select New query > Give a name >Click Define Query > From the drop down list select Custom Search> Click Advanced tab > Create a custom query by copy pasting the LDAP filter from QBDG to query the users..Right-click on your query and use Export List to save the result to .csv file..

Thanks for the info everyone. These are good suggestions for getting the members of one group.
We have hundreds and I was hoping for a scripted solution to pull all query based groups and members and dump them to a csv.

I found similiar solutions for regular groups, but not query based.

If you have Quest PowerShell for Active Directory then try the following script..I have not tested the code, but I think it should work..

$Groups = Get-QADObject -LdapFilter '(objectClass=msExchDynamicDistributionList)' -IncludedProperties msExchDynamicDLFilter -SizeLimit 0
   Foreach ($Group in $Groups){
	$Users = Get-QADObject -LdapFilter '$($Group.msExchDynamicDLFilter)' -SizeLimit 0
	    Foreach ($User in $Users){
		New-object PSObject -Property @{Group=$Group.Name;Member=$User.Name}
	   }
	}

Select allOpen in new window

It looks like the script is looping through and finding the groups, but outputs the following error.

Get-QADObject : Invalid filter format: '$($Group.msExchDynamicDLFilter)'
At C:\apps\powershell\questgetdlgroups.ps1:3 char:24
+     $Users = Get-QADObject <<<<  -LdapFilter '$($Group.msExchDynamicDLFilter)' -SizeLimit 0
    + CategoryInfo          : NotSpecified: (:) [Get-QADObject], LdapFilterException
    + FullyQualifiedErrorId : Quest.ActiveRoles.ArsPowerShellSnapIn.BusinessLogic.LdapFilterException,Quest.ActiveRole

This is exactly what I needed. IT did run for about 6 hours. It might be helpful to be able to specify an OU to cut down on the run time.
But, it got me what I needed. Thanks.

You can do that by adding a SearchRoot

$Groups = Get-QADObject -SearchRoot 'company.com/TestOU' -LdapFilter '(objectClass=msExchDynamicDistributionList)' -IncludedProperties msExchDynamicDLFilter -SizeLimit 0

OK, cool.
Thanks.
