If you wanted to enable send as a distribution group in Microsoft exchange you will be disappointed as this option is not available straight from the Exchange Management Console. But you can achieve this either setting up security permission from Active Directory Users and Computers or by applying a command on Exchange Management Shell.
Let’s see how to apply this.
1) Using active directory we are setting the send as permission for the distribution group named Executive.
2) The second way is to apply a one liner on the exchange shell.
Add-ADPermission -Identity ‘CN=Executives,CN=Users,DC=Contoso,DC=com’ -User “Contoso\Renjith” -ExtendedRights ‘Send-as’
