Send As permission for a mailbox is one of the most wanted features for secretaries in its Microsoft outlook to assist their Boss in sending mails on behalf, scheduling calendar, managing the contact etc. Here we go through on how to use grant send As permission for a mailbox using Exchange Management Shell and Active Directory Users and Computers. Once this permission is granted, any messages & calendar invite that are sent from the mailbox will appear as if they were sent by the mailbox owner.
[B]Things to note as part of preparations[/B]

- the account you use to perform this admin task must be delegated with "Exchange Organization Administrator role".
- You are not allowed to send e-mail messages on behalf of a mailbox if the mailbox is "hidden from address lists".
- Exchange Server needs that an e-mail address is resolved in the From field when you are sending mail on behalf. If the From address is set as "hidden from address lists" the SMTP address will not be resolved and is rejected.
