Dears;

Anyone can help in prevent group members to reply to restricted group in Exchange 2010.

I have a mail universal security group called (All-Users), and have another DL called (Test).

The (All-Users) DL accept messages from only sender (Test) DL.

The problem is when we create any other DL like (IT) DL and put it as a member in the (Test) DL, all users members in IT DL can send and reply to (All-Users) DL.

I want to prevent any groups members to reply or to sends to (All-Users) DL, without using the moderation option and without disable reply to all in outlook client.

Hello

its normal.

you need create new group for send to all-users group ad put only that user what need.
or create new rule and add only specified users who is can send to all-users 

Hello Sneff;

That's the problem, we already have a group for send to All-Users, it's called (Test) group and we have some of groups members in this (Test) group... the main issue is the groups members can reply and send to All-users group, we need to prevent these users to send or reply on All-Users group..

All-Users Group ------- accept messages from only sender (Test) DL--------IT DL member in (Test) DL ------ Users that members in IT DL can send and reply to All-Users Group, we need to prevent that..

Thanks for your concern..

Hello

create new rule. and drop all message
