Does anyone know of a way to use an 'Email Enabled Universal Distribution Group' as an external address (i.e. "SpecialPurposeAddress@thisdomain.net" ) for distribution of email to internal recipients defined by a 'Dynamic Distribution Group'?
I have found that when external email is sent to an email enabled Univ Dist Group which contains both an explicit single recipient ( firstname.lastname@example.org ) and a nested Dynamic Dist Group ( OganizationalGroup@thisdomain.net ) the message only gets delivered to the single recipient and not to any of the recipients within the Dynamic Dist Group.
Examining the receiver and content agent logs on the Edge Server I find instances of incoming messages but they only show the individual recipient as a recipient of the the message. From this I infer that the dynamic distribution groups are not being properly queried or resolved to individual recipients.
It is not clear to me after examining documentation whether or not the directory queries necessary for Dynamic Distribution Groups to be resolved to recipients can occur on an Edge server (ADAM based) or not. If this is not possible, could the problem be solved by forcing group expansion on a non-edge server?
Any hints on this subject from someone who's 'been there done that' would be greatly appreciated.
