You administer a Windows Essential Business Server (EBS) 2008 environment. All clients use the Messaging Server to send and receive e-mails. You want to configure a mailbox size limit for help desk users. You want to use the Set-Mailbox cmdlet for this purpose.

Which is the minimum Exchange administrator role you will require?

A.
the Exchange Organization Administrators role

B.
the Exchange Recipient Administrators role

C.
the Exchange View-Only Administrators role

D.
the Exchange Public Folder Administrators role

Explanation:
You will require the Exchange Recipient Administrators role. You can use the Exchange Management Console or the Exchange Management Shell to configure the default size limit for the Windows EBS mailbox. The Set-Mailbox cmdlet configures the size limit for existing mailboxes. You can configure the ProhibitSendReceiveQuota parameter in the Set-Mailbox cmdlet for this purpose. The ProhibitSendReceiveQuota parameter specifies the mailbox size at which the user associated with this mailbox can no longer send or receive messages. The account you use to run the Set-Mailbox cmdlet must be delegated the Exchange Recipient Administrator role.

All other options are incorrect because the account you use to run the Set-Mailbox cmdlet must be delegated the Exchange Recipient Administrator role. The Exchange Organization Administrators role gives administrators full access to all Exchange properties and objects in the Exchange organization. The Exchange Recipient Administrators role has permissions to modify any Exchange property on an Active Directory user, contact, group, dynamic distribution list, or public folder object. The Exchange View-Only Administrators role provides its members only read-only access to the whole Exchange organization tree in the Active Directory configuration container, and read-only access to all the Windows domain containers that have Exchange recipients. The Exchange Public Folder Administrators role provides its members the required administrative permissions to manage all the public folders.
