If you want to add the “send as” permission to distribution group, you can do this:

Use GUI:

1.     Went to the mail enabled security group in AD Users and Computers  and brought up the properties of the group

2.     Click on the security tab and added the security group and provided Send As permissions

OR

You can use the following cmdlet from Exchange Management Shell:
Add-ADPermission UniversalDistributionGroup -ExtendedRights Send-As -user UserWhoSends

 

For User

If you want to give the user “Bawin” the Send-As permission for the “Sajin” Mailbox you can use the following command line:

get-user -identity “sajin@shareitskills.com” | Add-ADPermission -User “bawin@shareitskills.com” -ExtendedRights Send-As

* In this case Bawin can send emails from his Outlook on behalf of Sajin if he is away.
