What is the script for send on behalf permission?
We have send as script for Send As: $access = "SendAs" $mailbox = Get-Mailbox -Identity MYSHAREDMAILBOX $identity = $mailbox.UserPrincipalName $permissions = Get-MailboxPermission -identity $id...
There is -GrantSendOnBehalf parameter on the Set-Mailbox cmdlet you could check out.
