Dynamic groups and powershell

Question

is there any way to create and configure dynamic groups via powershell script? I don't see any cmdlets in the management shell that address dynamic groups.

Assuming you have AR managing Exchange already, I believe you can set the VA edsaEstablishGroupEmail to TRUE for mail enabling the groups. There is a related flag edsva-MsExch-ApplyEmailAddressPolicy as well.

(concern) I strongly recommend to follow MSFT and do all Exchange management through Exchange door by calling Exchange ps1 cmdlets: this way you enforce Exchange-side policies. Contrary, by calling LDA/ADSI to manage Exchange attributes you may hit violation of Exchange-side policies. 
 Note, by setting Exchange related VA attribute via "QAD-xxx" cmdlet, AR might trigger Exchange cmdlets on back-end anyway (remote for EX2010 SP? and later).

We are on the same page here. 
 By setting in AR (MMC, WI, PS1 cmdlet) edsaEstablishGroupEmail, edsva-MsExch-ApplyEmailAddressPolicy - it forces AR to trigger EX PS cmdlet on back end. (AR design standard trick) >Assuming you have AR managing Exchange already, I believe you can set the VA edsaEstablishGroupEmail to TRUE for mail enabling the groups. That forces to respect EX side rules: >AR VA flag for following Exchange policy. Has this not always been there? This is supposed to force AR to observe the Exchange org's rules. and makes sense and great: >Exchange doesn't seem to like two objects in AD to have the same PrimarySMTP address :-) Support. Is it documented anywhere in AR manuals, SDK to use edsa VAs for the activity? if yes, then consultant passes all responsibility on AR engine, makes solution design clean, which is a right way.
