Nest mail enabled security groups.

Hi All,

I have mail enabled security groups in my environment. The mail enabled security group functions as a distribution group. Currently, the users are direct member to this security group. So:

Member of "Mail-enabled-security-group" = User1, User2, User3

I would like to nest the mail enabled security group to the role based group so i dont have to add new colleagues one by one every time. Yet looks like nesting mail enabled security groups does not work.  When i nest the group and try to mail to the distribution group i get "cannot perform the requested operation. the command selected is not valid for this recipient"

Any advice how to use nested distribution groups?

Thanks in advance.
