If you need to allow another user to send messages under the name of another mailbox, you can can grant ‘Send as’ permission.
When a user has ‘Send As’ permission they will be able to send an email using the name of the other mailbox. Any replies to the message will go to the other mailbox.
This is typically given to shared mailboxes, to centralise any replies to the sent messages.
