Hi @Roger Roger,

The Trustee parameter of Add-RecipientPermission can only add one user at a time. If you want to grant the send as permission to multiple users, you can refer to the following to create a CSV file:

$UserList = Import-CSV C:\temp\users.csv
ForEach ($User in $UserList) {
    Add-RecipientPermission distributiongroup -AccessRights SendAs –Trustee $user.alias
}

 

The Add-ADPermission command is the same as Add-RecipientPermission.

 

In addition ,I found this document for you reference:
