Two Exchange servers are located in the main office and are members of the Main Office administrative group.
The third Exchange server is located in the branch office and is a member of the Branch Office administrative group.
User and group accounts for users in the main office are located in the Main Office organizational unit (OU).
User and group accounts for users in the branch office are located in the Branch Office OU.
A new administrator is hired to perform the following administrative tasks: Create and delete user accounts for branch office users.
Add and remove users from mailenabled groups for branch office users.
Create and delete mailboxes on the Exchange server in the branch office.
