View Members Dynamic E-mail Group – Exchange 2010
Always nice to be able to check who a dynamic group contains. Easy to do from the powershell with these two commands:
[ps]
$DynGroup = Get-DynamicDistributionGroup "{name of dynamic distribution group}"
Get-Recipient -RecipientPreviewFilter $Dyn.RecipientFilter -OrganizationalUnit $DynGroup.RecipientContainer
[/ps]
