Shared mailboxes are useful to Helpdesk administrators and technical support staff, because all responses can be configured to go into a single mailbox that multiple users can access. The mailbox must be in a DRA managed domain with the Exchange Policy enabled, and you must have powers delegated to you to manage shared mailboxes.
When you create a shared mailbox, there are two types of permissions you can delegate to users: Send As and Full Access. Send As provides permission to read and send emails. You can delegate permissions to both user and group objects. You can also specify delivery restrictions, delivery options, storage limits, folder permissions, and several other options in the object’s properties.
Shared mailbox management is only supported in the Web Console.
