Ok, someone asked me the other day how to allow a user to send email as if they were the owner of another mailbox. This can be done by granting the user Send-AS permissions said mailbox – or you can even grant rights to send as a distribution group, very handy for members of a team.

One thing to note here is that Add-ADPermission cmdlet uses -Identity to classify the user who is assigned the permissions. You cannot use the mailbox alias for the -Identity and must use a unique display name or the distinguished name.

#Same as before but this time we know the display name is not unique so we are going to use the distinguished name:

Nice and easy. The process is the same for adding permission to a distribution group.

#Grant user Jane Doe permission to send from ALL distribution groups:

And lets say Jane changes roles and no longer needs to send on behalf of John…
