We are having an issue with Dynamic Distribution Groups. It seems as though there is no way to create them based on groups in ActiveDirectory. This would be much simpler than populating fields in AD accounts for 200+ users since we already have the groups created. If there is any way to do this I would appreciate any help.

Also, in AD we see an option for creating a new msExchDynamicDistributionList, but if we try this option it looks as though AD does not know what this item is after creation.
