  • What does group scope for Distribution groups imply?

    Hi all,

    I understand the group scopes for security groups, however what does configuring a group scope for distribution groups do?.

    In other words, how is a distribution group with a global scope, differ from a domain local scope or a universal scope?.

    For distribution groups, not a lot, although Exchange 2007 and above makes all new distribution groups universal in scope.

    In general Universal groups operate across domains so in a multiple domain environment, more traffic is generated with replication between GCs. AFAIK DL and Global DGs have no significant differences apart from the usual membership requirements.

      Thank you for your reply. So if I understand correctly -

      Domain Local DGs will accept members from any domain
      Global DGs will only accept members from their domain
      Wheras Universal DGs will accept members from any domain

      In other words, Universal DGs & Domain local DGs are pretty much the same as far as a user is concerned.

      And as far as universal groups are concerned, I have read that if you are using Windows server 2003 functional level, then only the changes to a universal group are replicated between DCs. So the traditional disadvantage of using them no longer holds good.
