    Thanks in Advance.

    Re: Groups

    In a nutshell: a security group is for setting ACL's on files and folders, etc. A distribution group is for sending email to a group of people. A security group may or may not be mail enabled. A distribution group must be mail enabled. A distribution group should not be used to set ACL's on files and folders, otherwise it will be converted to a mail enabled security group.

      Sorry Joe but I have a few corrections:

      - Distribution groups don't have to be mail enabled
      - You cannot assign permissions (i.e. set ACLs) to a distribution group... as least in Server 2003. There is no automatic conversion that I know of.

        Re: Groups

        Well pardon me then for giving bad info. Please shed some light on my understanding:

        1. How could a DG receive email if it is not mail enabled?
        2. You're correct about not setting ACL's on files and folders for a DG. I was thinking about setting permissions on Exchange Public Folders using DG's and the conversion from a UDG to a USG as referenced in the following articles:

        My apologies for not having all my facts straight.

          The simple answer is it can't for Exchange. But Distribution Groups are not there for the exclusive use of Exchange. Any application that can query AD can use Distribution Groups for whatever purpose it wants. It could use Security Groups for those same purposes of course but the same rules apply for why you would use a Distribution Group instead of a Security Group as when considering email distribution.
