I have DDG's that work that were created in Exchange 2003, but any I create in 2010 do not work!
I have tried with both the Shell and EMC. I am thinking there is something stopping the dynamic lookup, but at the same time I can get some lookup results. eg I have been able to create a group in EMC and click "Preview" and see the list of recipients, once. If I reopen the new group in EMC and preview again, the list is empty. I can however use the get-recipient command in the Shell and see the list of Recipients, but do not have a working list (mail sent to group is not received). I get similar results trying to create from the Shell.
I have tried using "Office", "Company" and "CustomAttribute1"
Event logs for MSExchange Management and Windows Powershell show the groups created successfully and do not show any errors.
Thanks in advance
