I have Exchange 2010 SP1 and it appears that I need to run this to query a dyn dist list for members
$group = get-DynamicDistributionGroup -identity "AJ.All.Staff"
Get-Recipient -LdapRecipientPreviewFilter $group.RecipientFilter
The 2nd line needs -LdapRecipientPreviewFilter apparently rather than –RecipientPreviewFilter (which works with 2007)
But it will not work. Please help me
