Despite its name, a shared mailbox provides access to more than just email. Like any Exchange account, a shared mailbox grants access to email, calendar, and contacts.
To add a shared mailbox in Outlook 2010, you must first be granted permission to access that shared mailbox. Your department might request a shared mailbox and designate a few employees to have access to it.
A shared mailbox allows you to work together with other staff members in shared environment. Changes made by one person are seen by others who have access to the shared mailbox. For example, if one person adds an event to the calendar for the shared mailbox, that event is accessible to the others. Likewise, if an email message was deleted from the Inbox by one person, it is deleted for the others as well.
