Hi Alma,The easiest way to prevent users from expanding DLs is to use the BCC field. Use bcc field for the DL instead of using the To or CC field.HTH.

Subject: [ExchangeList] Distribution List RestrictionHi,I create a distribution List name : EVERYONE and enable the message restriction. It will only accept message from testaccnt username. This will prevent other user to use the EVERYONE distribution list to send messge to everyone, when the userr received the mail and reply on the mail and expand the EVERYONE distribution, the EVERYONE distribution list will be treated as individual mail so they can still send message to everyone. My question is thier a way where i can disable sending mail to everyone one even they expand the everyone distribution list or disable expanding the everyone distribution list ?David
