what is shared mailbox?
A shared mailbox is a mailbox that multiple users can use to read and send email messages. Shared mailboxes can also be used to provide a common calendar, allowing multiple users to schedule and view vacation time or work shifts.
Why set up a shared mailbox?
Provides a generic email address (for example, info@contoso.com or sales@contoso.com), that customers can use to inquire about your company.
Allows departments that provide centralized services to employees (for example, help desk, human resources, or printing services), to respond to employee questions.
Allows multiple users to monitor and reply to email sent to an email address (for example, an address used specifically by the help desk).

Shared mailboxes are standard mailboxes that are accessed by multiple users.
Shared mailboxes are generally used as an contact point for enquires, projects or programs. For example, it may be the publicly listed contact for an organisation.
Although shared mailboxes must have an associated user account, this account is not used for log on in the domain and is disabled by default. Users who access the shared mailbox do so using access permissions.
