  • It is a complete functional mailbox, but it is not someone’s primary mailbox. Alternatively, it is a mailbox that anyone else (individual or group) who needs to monitor and might be able to reply. This functionality is used in almost every business.
  • A shared mailbox exclusively has no owner and also does not have its own password. Thus, no one can directly login to a shared mailbox. An admin can add you as a member of shared mailbox, and you can access either online or through the email client.
