Please assist with the PS command to convert DG into DDG. (or must Query-based DG be used?)

as per me there is no way.. you can create a new DDG with the custom filtering and go back to all those users and set the attribute..

you cannot convert a DG to a DDG, you need to create the a new group for the DDG

Hello,

Since each group would have a unique filter, it would not be efficient to script. Before you start replacing the current groups with DDGs, make sure you note the LegacyExchangeDN value of each group. You will want to add this value as an X500 address on the corresponding DDG so that users do not get an NDR when attemptig to send to cached entries of the old group.

See my article for an explanation of this - http://www.experts-exchange.com/Software/Server_Software/Email_Servers/Exchange/A_9650-NDRs-and-the-legacyExchangeDN.html

Very well. However, these DG's are new and currently hidden from GAL. But I'm looking for a way to create new DDG's from Bulk using csv, some based on who their manager's are, others based on work location and department.

Any thoughts on the PS script and the csv fields?
