Hi, I need to edit some distribution group to accept messages from new user. I tried with this: Get-DistributionGroup | where {$_.AcceptMessagesOnlyFromSendersOrMembers -ne $null} | Set-DistributionGroup -AcceptMessagesOnlyFromSendersOrMembers Rajco but that command set accept delivery only for new user(rajco) and I need to add this user and old to keep permision. Thank!

Hi Please take your time and ammend this to suite your requirements, this helps you ammend one distribution list, Iam sure you can modify to cater for more groups $DG = Get-DistributionGroup "Your Group" Get-DistributionGroupMember "tempDG" | foreach {$DG.acceptmessagesonlyfrom += $_.DistinguishedName} Set-DistributionGroup "Your Group" -AcceptMessagesOnlyFrom $DG.acceptmessagesonlyfromRegards Herbert Zimbizi

Hi Try the script below ---------------------------------------------------------------------------------------- $DGs = Get-DistributionGroup Foreach ($DG in $DGs) { $List = $DG.acceptmessagesonlyfrom $List+="Rajco" $DG | Set-DistributionGroup -AcceptMessagesOnlyFrom $List } ----------------------------------------------------------------------------------------- Cheers Zi Feng

Thanks Zi Feng, that script is working exactly what I need.
