You are the Exchange administrator for your company. Some user mailboxes are on servers that run Exchange Server 2003, and other user mailboxes are on servers that run Lotus Notes.
The Lotus Notes connector is installed on an Exchange server. The sales department has been partially migrated from Lotus Notes to Exchange Server 2003. In Active Directory,
you create a mail-enabled universal distribution group named SalesDepartment, to which you add all the Exchange mailboxes for users in the sales department.
The other users in the sales department have Lotus Notes mailboxes. These users are members of a Lotus Notes group named Sales.
Mail-enabled contact objects have been created in Active Directory for users who have Lotus
Notes mailboxes. A mail-enabled contact named Sales has been created in Active Directory for the Sales group in Lotus Notes.
Currently, when an Exchange user sends an e-mail message to the SalesDepartment distribution group, it is delivered to users in the sales department who have Exchange mailboxes,
but it is not delivered to users who have Lotus Notes mailboxes.
You need to ensure that Exchange users can send messages to all users in the sales department.
However,Exchange administrators must not be required to make changes when additional mailboxes are added to Lotus Notes for users in the sales department.
Your solution should minimize traffic between the Exchange servers and Lotus Notes servers.
What are two possible ways to achieve this goal? (Each correct answer presents a complete solution. Choose two.)

A.
In Active Directory, add the Sales contact object to the SalesDepartment universal group.

B.
In Active Directory, add the contact objects for sales department users who have Lotus Notes mailboxes to the SalesDepartment universal group.

C.
In Lotus Notes, create a contact for the SalesDepartment universal group. Add the contact to the Sales group on Lotus Notes.

D.
Instruct Exchange users to send messages to both the SalesDepartment universal group and the Sales contact when they need to send messages to the entire sales department.
