hi, Allusers@domain.com : Accept messages from CEOs group. CEOs group has members: CEO1, CEO2 FinanceDept@domain.com is member of allusers@dommain.com financedept@domain.com : Accept messages from financeadmin, financemanager In this situation, A mail from CEO1 to allusers@domain.com will not be delivered to members of financedept@domain.com members. Is this right?Those who are skilled in combat do not become angered, those who are skilled at winning do not become afraid. Thus the wise win before the fight, while the ignorant fight to win.

That is what I would expect to happen. Simon.Simon Butler, Exchange MVP. http://blog.sembee.co.uk , http://exbpa.com/
