i have mail-enabled members in a mail-disabled security group A. This group is a member of a mail-enabled security group B. If someone sends emails to group B, do the members in Group A receive the emails?

I don't think so though I have no test experience. It sounds like double forwarding. The problem is group A could not receive email, how could it pass the email message to members in GroupA? I think you need a test. Please don't hesitate to share your finding. thanks. Fiona Liao TechNet Community Support

Guangming, Rich Matheisen, Fiona_Liao: No, the message will not be delivered. When Exchange Server receives a message which appeared to be addressed to a mail-enabled group (no matter security/distribution) - the categorizer should expand that group to a list of valid recipients. And if it comes that the group contains not-mail-enabled subjects - they aren't processed in any manner. So in the questioned case - Exchange receives a message for "Group B", as there are no mail-enabled subjects discovered in that group and "Group A" member is not mail-enabled - the Exchange Servers stops processing the message. One even wouldn't get an non/delivery report on this case, unless specially requested from Outlook/owa. Vote if Helpful / Propose if Answer

No, that won't work. --- Rich Matheisen MCSE+I, Exchange MVP --- Rich Matheisen MCSE+I, Exchange MVP
