What is Shared Mailbox and how to use it?

A shared mailbox in Microsoft 365 is a mailbox that multiple users can access and use to send and receive emails. It is not associated with a single user's account and does not have its own username and password. Instead, it is typically used for a specific purpose, such as a team or departmental mailbox, and multiple users are granted permissions to access it.
