A key difference between a shared mailbox and a user mailbox in terms of licensing is that a user mailbox requires a separate license for each user to access it, while a shared mailbox does not need a dedicated license; users can access a shared mailbox with their existing Exchange Online license, meaning only the user accounts accessing the shared mailbox need licenses, not the shared mailbox itself.
