Can we go back to preventing users from Creating Globally Visible Distribution Lists as a default? Yes, I know there are workarounds, but it would just be better if this never was allowed to begin with.
Users can manage Distribution groups, but can only add members who have an AD object.
For example : Add a second multi-value attribute (eg externalMembers) and a permissions mask to provide the ability for an administrator to allow certain DGs to have a secondary list of external SMTP addresses.
Why not make actual "automatic" out of office replies based on user connectivity and automatically forward to any of the following:
> The distribution group the user belongs to (Small groups)
> User Selected member(s) of his/er distribution group (Larger Groups)
> User Selected member(s) (Non grouped users)
> Administrator Selected member(s) (Non grouped users)
